摘要
非结构网格因其在处理外形方面所具有的特殊优越性而倍受关注 .在结构 非结构网格中做了粘性流动的数值优化计算 ,优化计算包括单目标和双目标气动优化 ,以及反设计计算 ,即从初始翼型不断修型而实现给定翼型的外形及压力分布的目标 .算例及其结果分析证明了该方法用于翼型的修型和设计计算的有效性 .
Attention has been paid by researchers to the unstructured grid method for complex configuration. Numerical optimization and inverse design computation with the viscous flow field were carried out on a structured/unstructured grid. Both mono-objective/bi-objective aerodynamic optimization were included in the numerical optimization. The conventional inverse design, in which the airfoil shape is modified by the required target pressure distribution imposed on initial airfoil, is realized by the optimization method.
