Aerodynamický výpocet vzduchové části parního kotle / Aerodynamic Calculation of Air Part of Steam Boiler

Kudela, Libor January 2017 (has links)
The aim of this thesis is to realize analysis of problematics of aerodynamic calculations of steam boilers on the part of combustion air. On the basis of project documentation realize evaluations of sectional dissipation factors of each component of inlet tract. Realize calculation of summary pressure (draft) loss. Specify components with highest loss and propose options of their optimization.

Experimentální identifikace aerodynamických vlastností vozidla jízdní zkouškou / Experimental identification of aerodynamic characteristics of a vehicle by on-road test

Poláš, Maroš January 2017 (has links)
This thesis deals with road loads, coastdown tests and evaluation of measured data. Thesis consists of two main parts: theoretical and computational. The first part describes road loads with focus on aerodynamic drag and lift force. In the second part, a software tool for processing the measurement per ISO 10521-1 is designed and lift force measured with running resistance method is calculated.

Výpočtové modelování aerodynamického hluku způsobeného bočním zrcátkem automobilu / Computational modelling of aerodynamic noise caused by the car’s side mirror

Vobejda, Radek January 2019 (has links)
The master’sthesis deals with numerical modelling of aerodynamic noisewhich arisesinside of the carcabin. In the first part ofthe thesis simplified model of geometry of the car and of the inside acoustic pressure arecreated. After that numerical analysis of created models of geometry are doneandvarious models of turbulenceare discussed. The results of these CFD simulationswhere then used for changing the model of geometry of the wing mirror. Outputs of these simulations were used for solving the numerical analysis of noise in the car cabin.

Využití reverzního inženýrství pro výpočty aerodynamiky automobilu / The utilization of reverse engineering in computation of vehicle aerodynamics

Rozsíval, Jan January 2008 (has links)
The vehicle body was measured by using ATOS 3D scanner. Measured data from the ATOS 3D scanner were applied to make a 3D model of vehicle body and to make a 3D model of whole vehicle by using computer program Pro/ENGINEER. The model of vehicle was made with a view for future use of CAD model. Surface of the vehicle model was used for computation of vehicle aerodynamics – aerodynamic static pressure distribution by using CFD software Star-CCM+.
