基于气动反问题的扩压叶栅优化设计
Optimization Design of Diffusive Cascades Based on Aerodynamic Inverse Problem
摘要
Abstract
The blade aerodynamic inverse problem is adopted to obtain the new optimized blade profile by selecting the optimal blade surface pressure distribution and finite number of steps of blade profile correction. The results show that it is feasible to calculate the optimal pressure coefficient distribution by Head boundary layer thickness calculation method and optimization algorithm. Suitable blade profile designed by the"elastic model"illustrates that the modified method is successful. The inverse problem established is effective and has good practicability and reliability.关键词
