Numerical Airframe Aerodynamic Performance Prediction: An Exergy Point of View.

Abstract

The prediction of the aerodynamic performance of airframe has been historically made via the determination and decomposition of the force opposing the aircraft motion: drag. The paper presents an innovative energy approach which is based on the destruction of exergy by irreversible processes. A required step in the development process is to validate its numerical implementation via various CFD test cases: 2D aerofoil and 3D wing RANS test cases are presented in subsonic and transonic regimes. Mesh convergence studies prove the exergy approach to have a similar accuracy as the traditional near-field drag approach while offering a phenomenological breakdown comparable to a far-field formulation.
