| 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. |
