Abstract

This research examines the feasibility of reducing the time to solution for a high-fidelity, blade-resolved CFD simulation of a wind farm using Tenasi. The intent is to reduce the overall cost by initializing the flow fields of the individual turbines in the wind farm using a steady state or an unsteady simulation of a single turbine. This is achieved by replicating the mesh and the solution corresponding to a single turbine repeatedly, thus initializing the solution for the entire wind farm. The wind farm consists of the DTU 10 MW Reference Wind Turbines. Results compared to the “from scratch” solutions shows a 25 – 50% reduction in computational cost for steady simulations. For unsteady simulations, it is hypothesized that the savings could be on the order of 70%.

Acknowledgments

I would like to express my gratitude to my advisor, Dr, Kidambi Sreenivas, for his support, patience, and encouragement at each and every step of this memorable journey. My thanks also go to the members of my dissertation committee, Dr. Lafayette Taylor, Dr. Stephen Nichols for sharing their knowledge and providing useful suggestions at various stages of my MSc. I would also like to thank Dr. Timothy Swafford his guidance at various stages of my graduate life at SimCenter. Finally, I would like to thank each and every member of the SimCenter for providing a friendly and healthy atmosphere for the research. The support of UT SimCenter at Chattanooga is greatly acknowledge. I was fortunate to have had the opportunity to work and study alongside the team at SimCenter. I would also like to thank my loving parents, Elhadi and Salma Hassan for all the encouragements they gave me to perceive this degree. Their patience and encouragement during all the highs and the lows of this research was essential. I would also like to thank my supporting friends for their endless support during the last 2 years.
