Acceleration Of Cfd And Data Analysis Using Graphics Processors, Ali Khajeh Saeed
Acceleration Of Cfd And Data Analysis Using Graphics Processors, Ali Khajeh Saeed
Open Access Dissertations
Graphics processing units function well as high performance computing devices for scientific computing. The non-standard processor architecture and high memory bandwidth allow graphics processing units (GPUs) to provide some of the best performance in terms of FLOPS per dollar. Recently these capabilities became accessible for general purpose computations with the CUDA programming environment on NVIDIA GPUs and ATI Stream Computing environment on ATI GPUs. Many applications in computational science are constrained by memory access speeds and can be accelerated significantly by using GPUs as the compute engine. Using graphics processing units as a compute engine gives the personal desktop computer …
The Aerodynamics And Near Wake Of An Offshore Floating Horizontal Axis Wind Turbine, Thomas Sebastian
The Aerodynamics And Near Wake Of An Offshore Floating Horizontal Axis Wind Turbine, Thomas Sebastian
Open Access Dissertations
Offshore floating wind turbines represent the future of wind energy. However, significant challenges must be overcome before these systems can be widely used. Because of the dynamics of offshore floating wind turbines -- surge, sway, heave, roll, pitch, and yaw -- and the resulting interactions between the rotor and generated wake, the aerodynamic analysis methods and design codes that have found wide use throughout the wind energy industry may be inadequate. Application of these techniques to offshore floating wind turbine aerodynamics may result in off-optimal designs, effectively handicapping these next-generation systems, thereby minimizing their full potential. This dissertation will demonstrate …
