| Abstract: | Based on an Euler solver,the complex powered high-lift flows with the externally blown flap(EBF) concept of transport aircraft was numerically simulated.With the optimization of assemble between engine and flap,the predictive capability of the Euler method for powered lift characteristics has been preliminary assessed.The computational results show that the Euler solver is a good choice for the powered high-lift configuration in the conceptual design stage. |
