一种跨音速翼型和机翼设计方法的新进展

CFD SOFTWARE FOR TRANSONIC AIRFOIL AND WING DESIGN—AN UPDATE Hua Jun, Zhang Zhongyin

讨论一种基于Ｎ－Ｓ方程、欧拉和速势方程加混合附面层修正的跨音速流动准确控制方程逆解法，及其在跨音速翼型和机翼设计中的应用。分析了两种紊流模型对分离的适应性，探讨了Ｎ－Ｓ和欧拉方法的阻力估算精度问题，列举了若干超临界和层流翼型及机翼的设计实例以及软件验证。

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.
