PhD Research

Large Eddy Simulation Studies of Wind Turbine Wakes in Complex Terrain

PhD Advisor Information:

Dr. Niranjan S Ghaisas (Google Scholar)

Department of Mechanical and Aerospace Engineering

Indian Institute of Technology, Hyderabad

Scope of Research:

1. Develop a numerical tool enabling simulations of the atmospheric boundary layer and wind farms over complex terrain

2. Understand the turbulence in the wind farms as a function of the changes in elevation and roughness properties of the bottom boundary

3. Develop analytical models for predicting the mean wind speed and power generated by a wind farm sited on non-flat, heterogeneous terrain.

The contour plot and velocity profile over a Cosine Squared hill is shown below in the figure.
