An analytical model of a vertical axis wind turbine was implemented using both a 2-D and a 3-D vortex model. The model requires significant amounts of computational resources and time compelling the use of an improved method for executing the algorithm in a highly parallelized fashion. Graphics Processing Units (GPUs), which are a new highly cost effective method of implementing parallel processing, were used along with a interface code to allow the numerically intensive routine to execute as parallel code on a graphics card. This achieved a substantially reduced computation time compared to a traditional desktop computer model. Using two quad-core processors and a graphics card, a 19.7 fold reduction in computation time was achieved. This paper will describe the model used, the parallel code created, the GPU interface, and an illustration of the performance increases.
