Submersíveis em velocidade constante e pequenas cotas de submersão são aqui considerados e os efeitos da superfície livre no fluxo são levados em conta. O problema de geração de onda devido ao avanço de corpos submersos é abordado no presente estudo. Neste problema de contorno, as condições de superfície livre são linearizadas. A formulação diferencial é condicionada como um problema de integração através da aplicação da segunda identidade de Green. A discretização do problema conduz a um sistema linear no potencial de velocidades, que se supõe ser distribuído através de B-splines parabólicas nos painéis. A contribuição desta dissertação tem foco em propor diretrizes para a aplicação do método descrito em condições operacionais típicas de cascos de submarinos em movimento de avanço em cotas periscópicas de submersão. Os resultados numéricos obtidos através destes procedimentos são comparados a resultados publicados existentes para sua de validação. / Submersibles in constant ahead velocity at small submergences are here considered, the free surface effects on the flow are taken into account. The wave generating problem due to submerged bodies advance is addressed in the present study. In this boundary value problem, the free surface conditions are linearized. The differential problem is conditioned into an integral problem through the application of Green\'s second identity. The discretization of the problem leads to a linear system in the velocity potential, that is supposed to be distributed according to parabolic B-splines into the panels. The contribution of this dissertation focus on guidelines for the application of the above method on typical operational conditions of submarine vessels under ahead motion at snorkelling submergences. The numerical results obtained through these procedures are compared to existent published results with the aim of validation.

The concept of marine current turbines was developed by Peter Fraenkel in the early 1970s. Ever since Fraenkel's efforts to modify and test the technology, several worldwide agencies have been exploiting the technology to retrofit the marine current turbine to their particular application. The marine current turbine has evolved from generating a few kilowatts to a few gigawatts. The present study focuses on a megawatt sized turbine to be located offshore the coast of Ft. Lauderdale, Florida. The turbine is to be placed in a similar location as a 20 kW test turbine developed by the Southeast National Marine Renewable Energy Center (SNMREC) at Florida Atlantic University, Dania Beach, FL. Data obtained from the SNMREC is used in the mathematical model. ANSYS FLUENT is chosen as the CFD software to perform wave-current interaction simulation for the present study. The turbine is modeled in SolidWorks, then meshed in ANSYS ICEM CFD, then run in FLUENT. The results obtained are compared to published work by scholarly articles from Fraenkel, Barltrop and many other well known marine energy researchers. The effects of wave height on the turbine operation are analyzed and the results are presented in the form of plots for tip speed ratio and current velocity. / by Amit J.
