Airfoil optimization using Design-by-Morphing [PDF]
Journal of Computational Design and Engineering, 2023 Abstract Design-by-Morphing (DbM) is a novel design methodology that creates a search space for topology optimization. Traditional design techniques often impose geometric constraints and, sometimes, the designer’s biases on the design space, which restricts the novelty of the designs and allows for only small local changes.

Airfoil GAN: encoding and synthesizing airfoils for aerodynamic shape optimization
Journal of Computational Design and Engineering, 2023 Abstract The current design of aerodynamic shapes, like airfoils, involves computationally intensive simulations to explore the possible design space. Usually, such design relies on the prior definition of design parameters and places restrictions on synthesizing novel shapes.

Aeroacoustic airfoil shape optimization enhanced by autoencoders
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.
