摘要: 将计算流体动力学(CFD)与最优化技术相结合,通过数值求解欧拉方程,对翼型绕流流场作出了数值模拟.再利用几何、流动和最优化控制方程,反复迭代求得在一定约束条件下气动性能最优的翼型.本文以NACA0012为原始翼型,选取两种设计工况,都取得了满意的结果.

Abstract: Computational Fluid Dynamics(CFD) and optimization technique are combined in this paper for the purpose of optimal aerodynamic design of transonic airfoil. In this method, 2-D Euler equations are numerically solved to simulate the flow around airfoil using finite volume method, then geometric conditions, optimization equations are implemented to modify the airfoil through shape functions. The two steps are iterated until optimal aerodynamic performance of airfoil is achieved under certain conditions. Two cases, both based on the original airfoil of NACA0012, are presented to show the efficiency of this method.
