Aerodynamic Inverse Design Framework using Discrete Adjoint Method

Abstract

The aerodynamic inverse design approach consists of finding the ge-ometry that produces a desired (target) pressure distribution. Such design problem is here solved using optimization strategies based on CFD solver to minimize the pressure residual. It is observed that the key ingredients for solving this problem are the mesh point parametrization combined with the adjoint approach for effi-cient and reliable design. The resulting optimization framework is finally success-fully assessed on representative 2D design problems ranking from viscous sub-sonic to inviscid supersonic flows.
