Aeroacoustic airfoil shape optimization enhanced by autoencoders [PDF]
Expert Systems with Applications, 2022 We present a framework for airfoil shape optimization to reduce the trailing edge noise for the design of wind turbine blades. Far-field noise is evaluated using Amiet's theory coupled with the TNO-Blake model to calculate the wall pressure spectrum and fast turn-around XFOIL simulations to evaluate the boundary layer parameters.
