摘要
基于Euler方程来数值模拟运输机吹气襟翼的流动机理,通过优化发动机及襟翼系统的安装,以此评估其动力增升效果。计算结果分析表明本文方法对动力增升概念设计有很好的适用性。
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.
