Abstract:

A transonic airfoil and wing design software is presented based on the solutions of the N S equations, Euler and potential equations. plus mixed boundary layer methods. The applicability of two turbulent models to the flow with separation and the accuracy of the drag calculation with N S and Euler solvers are also investigated. Design examples and code validation are discussed.

Key words: NavierStokes equation, Euler equation, inverse problem, aerodynamic design, code validation
