Challenging the Versatility of the Tesla Turbine: Working Fluid Variations and Turbine PerformanceJanuary 2012 (has links)
abstract: Tesla turbo-machinery offers a robust, easily manufactured, extremely versatile prime mover with inherent capabilities making it perhaps the best, if not the only, solution for certain niche applications. The goal of this thesis is not to optimize the performance of the Tesla turbine, but to compare its performance with various working fluids. Theoretical and experimental analyses of a turbine-generator assembly utilizing compressed air, saturated steam and water as the working fluids were performed and are presented in this work. A brief background and explanation of the technology is provided along with potential applications. A theoretical thermodynamic analysis is outlined, resulting in turbine and rotor efficiencies, power outputs and Reynolds numbers calculated for the turbine for various combinations of working fluids and inlet nozzles. The results indicate the turbine is capable of achieving a turbine efficiency of 31.17 ± 3.61% and an estimated rotor efficiency 95 ± 9.32%. These efficiencies are promising considering the numerous losses still present in the current design. Calculation of the Reynolds number provided some capability to determine the flow behavior and how that behavior impacts the performance and efficiency of the Tesla turbine. It was determined that turbulence in the flow is essential to achieving high power outputs and high efficiency. Although the efficiency, after peaking, begins to slightly taper off as the flow becomes increasingly turbulent, the power output maintains a steady linear increase. / Dissertation/Thesis / M.S.

Project Loveday : Föreställningar i fan-producerade reklamfilmer. / Project Loveday : Futuristic imaginations in fan-produced commercials.Hetting, Johan, Bouveng, Oskar January 2018 (has links)
Tesla är ett multinationellt företag som tillverkar och säljer elbilar bland många andra produkter och tjänster. Vår studie kommer primärt fokusera på Tesla Motors, den del av företaget som producerar och säljer bilar. Tesla är inte ett traditionellt företag när det gäller reklam och marknadsföring då de aldrig har marknadsfört sig via traditionella mediekanaler som TV-reklam, tidningar eller radio. Istället förlitar de sig på sina fans, och använder deras sociala mediekanaler för marknadsföringsändamål. Eftersom Tesla är ett modernt och tekniskt företag som får stor uppmärksamhet runt om i världen är det inte konstigt att människor finner företaget och deras produkter intressanta, därav har en fan-gemenskap vuxit kring upp företaget. Fandom är en kultur baserad på ett gemensamt intresse kring ett visst ämne eller en specifik sak. Kulturen är byggd på gemenskap och ett gemensamt intresse kring ämnet i fråga där fansen delar samma värden. Syftet med fandomproduktioner är inte att tjäna pengar, utan att dela materialet med andra personer som har samma intresse för ämnet. Tesla är medvetna om att det finns en stark fangemenskap runt företaget, vilket ledde till att de lanserade "Project Loveday" - ett projekt där deras fans fick möjligheten att skapa egna Tesla-reklamfilmer som senare skulle sändas och publiceras på Teslas egna hemsida. Syftet med vår studie är att få fram vad Teslas fans och entusiaster vill kommunicera i sina egenproducerade filmer under kampanjen “Project Loveday”. Detta kommer göras genom att vi besvarar våra frågeställningar som innefattar hur fans och entusiaster framställer Teslas elbilar i sina egenproducerade filmer, samt vilka futuristiska konnotationer, symboler, ideologier, och myter som syns i dessa filmer. Med hjälp av semiotisk analys som metod kommer vi kunna tolka de olika tecken som förekommer i de utvalda filmerna, samt analysera dess innehåll på ett begripligt sätt för att sedan skapa en djupare förståelse kring vad man försöker förmedla. Studiens resultat visade att de föreställningar kring framtiden som förekommer i Project Loveday innefattar associationer till rymden och den teknik den bär med sig, samt att Tesla Motors besitter denna teknik och därmed kan ses som en del av framtiden. / Tesla is a multinational company which manufactures and sells electric cars among many other products and services. However, our study mainly focuses on Tesla Motors – the part of the company which produces and sells automobiles. Tesla is not a traditional company when it comes to advertisement or marketing – they have never advertised themselves through traditional media channels such as TV-commercials, newspapers, or radio. Instead they rely, and use their own fans and consumer’s media channels for marketing purposes. Since Tesla is such a modern and technological company which gets a lot of attention around the world, it is not strange that people find them and their products interesting. Therefore, a fan community has grown around the company. Fandom is a culture based on a mutual interest about a certain or specific matter. The culture is based on community, values and a shared interest in the subject. The purpose is primarily so share material with people with the same interest, not to profit on it. Tesla is aware that they have a strong fan community, which led them to launch “Project Loveday” – a project where their fans got the possibility to create their own Tesla commercials which later would be broadcasted and posted on Teslas own website. The purpose with this study is to obtain what Teslas fans and enthusiasts wants to communicate in their own produced movies in the “Project Loveday” campaign. This will be done by answering our questions of issue, which includes how fans and enthusiasts presents Teslas electric cars in their own produced movies, as well as what kind of futuristic connotations, symbols, ideologies, and myths that can be seen in these movies. By using semiotics as our choice of method we will interpret the different signs which occurs in the chosen movies, and analyze their content in an understandable manner regarding what they try to mediate. The result of the study shows that the perceptions about the future which occurs in “Project Loveday” includes associations to space, and the technique it brings along. It also shows that Tesla possesses this technique and therefore can be seen as a part of the future.

“Teslafamiljen” : En studie om huruvida kommunikation kan påverka konsumenters tillhörighet till ett företagRodmark, Moa, Cederäng, Josefin January 2017 (has links)
ABSTRACT AIM: Consumers are to some extent more interested in being a part of a brand community rather than interested in the actual product the company are selling. In addition, the aim of this study is to examine Tesla’s communication to its consumers and whether the communication can affect consumers' feeling of being a part of the company. The study will investigate consumers' perception of the communication. METHOD: The empirical method used in this study was a survey distributed on four Facebook groups with a special interest in Tesla and a Swedish discussion site about the company, which generated a total of 217 individual answers. MAIN RESULTS: The main results of the study show that Tesla's consumers perceive Tesla’s communication as both innovative and modern. Even though the consumers perceive word-of-mouth in Tesla's communication, they do not see it as part of the company’s marketing. It is primarily product-oriented factors such as environment and technology development that attracts consumers to Tesla as a company. There is also an emotional interest in Tesla’s electric cars, feelings of safety, pleasure in driving and sense of freedom were in focus when discussing the car. Further the study shows that interaction and connection among consumers are key to make the customers feel a part of the Tesla community. The results provide an increased understanding about the meaning of communication and how it can provide an interaction with customers.

“LIVE, BREATHE, TESLA” : En kvalitativ studie om gemenskap och kundlojalitet i Teslas svenska Facebook-communityBakir, Shajan, Olai, Joel Arvid January 2024 (has links)
The primary objective of the research was to examine the motivations behind members’ participation in Tesla’s online community on Facebook and explore how member interaction influences engagement and loyalty towards Tesla. The emergence of new technologies has intensified the complexity of understanding user behaviors. This study contributes to an enhanced understanding of how individuals utilize media to fulfill various needs, impacting behaviors and attitudes. Previous research indicates that online community participants seek belonging, information, social interaction, entertainment, and self-realization. Active involvement, information sharing, and stronger relationships within brand communities enhance consumer-brand relations and serve as exit barriers. Therefore, three research questions were formulated to shed light on members’ motivations for participation, their level of involvement, relationships within the community, and their impact on customer loyalty. Positioned within popular culture studies and with a framework consisting of Brand Community Theory and Uses and Gratifications Theory, a qualitative content analysis was conducted on 10 semi-structured interviews. Findings suggest varying motivations for participation, with primary emphasis on gathering product information. Active engagement through knowledge-sharing fosters a sense of unity and heightens involvement. The social interaction among Tesla enthusiasts not only enhances engagement but also cultivates customer loyalty by fostering meaningful relationships. Members' roles as "working consumers", and Tesla’s responsiveness to suggestions, positively influence customer loyalty, reinforcing the community's value. However, member passivity due to negativity or unfulfilled entertainment needs can result in diminished engagement and subsequently affect customer loyalty negatively.

Equacionamento e modelagem da bobina bifilar de tesla e proposta da sua utilização como um sensor biotelemétrico autorressonanteMiranda, Caio Marcelo de 19 June 2012 (has links)
CAPES e CNPq / A Biotelemetria apresenta-se como uma importante técnica que possui várias aplicações na área de Engenharia Biomédica e outras. A miniaturização da unidade sensora é um grande desafio dentro desta área, sendo que na maioria dos casos, deseja-se uma unidade menor possível. Desta maneira, sensores passivos são interessantes, pois possibilitam uma menor dimensão do dispositivo e não necessitam de uma fonte própria de energia, ou bateria, que pode causar danos ao indivíduo monitorado caso ocorra vazamento do seu conteúdo químico. Deste modo, o sensor indutivo autorressonante apresenta-se como uma promissora solução, uma vez que este pode ser construído com apenas um componente, um indutor, que utiliza a sua própria capacitância parasita no lugar de um capacitor externo. Por apresentar pequenas dimensões, este tipo de sensor possui uma baixa capacitância parasita, o que torna a sua frequência de ressonância bastante alta. Isso pode resultar em alguns problemas e até mesmo inviabilizar o projeto. Neste caso, a bobina bifilar idealizada por Nikola Tesla pode ser uma solução, uma vez que o objetivo de Tesla foi aumentar a capacitância intrínseca de suas bobinas. Portanto, um entendimento físico e devido equacionamento da bobina bifilar se faz necessário, uma vez que, até onde se sabe, este tipo de abordagem não existe na literatura. A partir de uma análise física em função das tensões entre espiras adjacentes da bobina bifilar de Tesla, foi desenvolvido um equacionamento que possibilita a determinação do aumento da capacitância interna e, consequente, redução na frequência de ressonância da bobina bifilar. Um modelo elétrico equivalente da bobina também foi elaborado através desta análise. Testes foram realizados para validar a análise física, e comparar a frequência de autorressonância calculada e medida para diversos números de espiras, de modo a comprovar a validade do modelo e das equações desenvolvidas. Um sensor biotelemétrico indutivo autorressonante, para medição de deslocamentos, utilizando a bobina bifilar de Tesla, foi desenvolvido para caracterizar a sua utilização como um sensor biomédico. / Biotelemetry is an important technique with many applications in biomedical engineering and other areas. The size of the remote unit or sensor is a major challenge in this area, and, in most cases, a sensor is desired to be as small as possible. Thus, passive sensors are interesting because they allow a smaller dimensions and do not require a power source or battery, which can harm the patient in the event of leakage of its chemical content. Thus, the self-ressonant inductive sensor is a good solution since it can be built with only one component. Due to its small size, this type of sensor has a low stray capacitance, which makes its self-resonance frequency very high. In this case, the bifilar coil, devised by Nikola Tesla, can be a solution, since Tesla's idea was to increase the intrinsic capacitance of his coils. Therefore a physical understanding of the bifilar coil is necessary, since as far as is known, this approach does not exist in the literature. From an analysis of the voltage between adjacent turns, equations of the Tesla's bifilar coil were developed, allowing the prediction of the increase on the internal capacitance and consequent reduction of the resonance frequency. An equivalent electric model was also developed from this analysis. This allowed the project of bifilar coils and the calculation of the internal capacitances and self-resonance frequencies of these coils. Tests were realized in order to compare the calculated and measured self-resonance for various numbers of turns, showing the validity of the presented method. A passive self-resonant biotelemetric sensor for displacement measurement using the Tesla's bifilar coil, was also developed.
