遗传算法在离心压缩机参数优化中的应用

遗传算法是当今世界上应用比较广泛的优化算法之一，特别是在处理有界多极值复杂函数方面有着明显的优势．在流体机械行业中，设计参数的优化问题往往涉及求解一些复杂隐函数在约束区间内的极值问题．因此将遗传算法应用到流体机械的设计参数优化当中有明显的现实意义．本文介绍了遗传算法在离心压缩机参数优化中的应用，并与传统的复合型法所获得的优化结果进行了比较，对比的结果显示出了遗传算法的优越性．

AN APPLICATION OF GA IN CENTRIFUGAL COMPRESSOR'S OPTIMIZATION

Now days, GA is very popular in the world, especially in the field of optimizing limited complex function. In designing of turbomachine, designers always have to optimize some complex function in limited fields, so it is important to introduce GA in the turbomachinary-designing field. In this paper, we give an detail application of GA in centrifugal compressor's optimization, the results tell us that GA is better than those traditional optimization methods such as complex.
