摘要
本文发展了一种符合完全黏性假设的叶型逆命题气动设计方法,该方法采用目标和当前压力分布的差计算一个虚拟速度驱动网格变形,直到获得满足目标压力分布的型线。将上述方法通过UDF与FLUENT软件结合搭建了逆命题设计平台,采用动网格技术实现叶片表面网格变形。采用本平台对一组叶栅和两组翼型进行逆命题计算验证,证明了本平台对于内流和外流问题的有效性。
An inverse aerodynamic design method for blade shape under real viscous conditions is developed in the paper.In this design method,the mesh deformation is driven by the virtual velocity computed from the difference between the target and current pressure distributions,with the aim to making the blade shape have the prescribed pressure distribution.The inverse design platform is then constructed through implementing the inverse design method into FLUENT using the User-Defined Function.The dynamic mesh technology is used to realize the movement of the blade surface grid.The inverse design is conducted for a parabolic cascade and two airfoils based on the inverse design platform and its effectiveness for both the internal and external flows is validated.
