However , the simulated annealing algorithm will expand too much time to estimate the values of objective function when applied to aerodynamics optimizations . the way to remedy this problem in this dissertation is by improving the efficiency of optimizer and the cfd - solver . our cfd - solver is base on the modification to the proper orthogonal decomposition ( pod ) method that can produce a finite series of basis functions or modes through the solution of snapshots 但对于气动外形优化设计问题来说,由于评估需要解决的问题的目标函数值需要多次调用流场解算器,会导致用模拟退火算法进行优化设计的计算工作量过大,因此需要我们对流场解算器和优化方法两个方面进行研究以寻找此问题的解决办法。
