Turbine Load Assessment for Thunderstorm Downbursts using LES

• Generated thunderstorm-related inflow fields for a wind farm using LES model in UNIX supercomputer and                estimated wind turbine loads using the aeroelastic response simulator, NREL FAST.

Stability Analysis of a Constrained Shallow Arch

• Modeled a half-sine arch constrained by a rigid plate and subjected to concentrated moments based on Euler beam theory. 

​

• Developed an original modification of energy method to treat the stability problem taking into account the constraints.

​

• Constructed a computational system in Mathematica to control numerical convergence and conduct the bifurcation analysis of multiple equilibrium solutions.

​

• Experimental measurement and correlation with theoretical prediction.
