| 摘 要： | 用遗传优化算法结合流线曲率法管流流场求解器建立了一种多级压气机多目标气动优化设计方法.优化目标为总压比和绝热效率最大,决策变量为转子和静子叶排尾缘速度环量.测试结果表明,该优化算法的搜索效率和全局性都较好.用该方法对一台5级高压压气机进行了气动优化设计,压气机性能有了明显提升.

| Abstract: | A multi-objective aerodynamic optimization method is developed using genetic algorithm and duct-flow code that employs streamline curvature approach.Velocity circulations at the trailing edges of each blade-row are optimized for overall maximization of total pressure ratio and isentropic efficiency.The test indicates that the optimization algorithms can auto-search for optimal result globally and efficiently.A five-stage high pressure compressor is redesigned by using this method and the performance is enhanced greatly. |
