Ph.D. Illinois Institute of Technology

Developed a computational fluid dynamics (CFD) multiphase model by coupling the Discrete Phase Model (DPM) and the Volume of Fluid (VOF) models to simulate the motion of rain droplets and capture the resulting continuous water layer formation over structures under rainy conditions.

Developed User Defined Functions (UDFs) to implement our model into the ANSYS Fluent code to investigate the effect of rain on performance of airfoils and wind turbines operating under rainy conditions.

Developed two different expressions to model the momentum that raindrops add to the water layer formed around structures under rainy conditions.

CFD simulation of turbulent flow around NREL phase VI wind turbine at various wind speeds.

CFD simulation of single and multiphase turbulent flow around S809 airfoil at various angles of attack, rainfall rates and surface properties.

Experimental Data Analysis of a Wind Turbine in Grand Ridge Wind Farm, La Salle County - Illinois, to investigate the effect of rain on its power output.
