Shape optimization of NACA0012 using ANN-based surrogate model. The “Hicks-Henne bump function” has been used to parameterise and deform the original shape according to design parameters. Sampling parameters are generated using quasi-random low-discrepancy sequences called “Sobol” sequences. Numerical simulations have been conducted using the potential flow-based panel method solver “XFOIL” to obtain lift and drag coefficients of deformed foil shapes. An ANN-based surrogate model has been trained to predict the lift-coefficient and drag-coefficient corresponding to design parameters. The Python library “scipy. optimise.minimize” has been used to optimise the surrogate model on the basis of objective functions to obtain optimal design parameters.
