摘　　要：本文应用响应面方法完成了某叶片扩压器的优化设计。通过改变叶片数和出口安装角构造扩压器,进行CFD分析,建立样本数据。基于不同的样本数,用响应面方法寻求的最佳设计点在大致相同的区域,而且与CFD分析结果相比误差很小。表明,响应面方法可以通过较少的样本准确拟合设计变量与响应变量的关系,在流体机械性能预测和多变量优化设计问题中有很好的应用前景。In this paper, the optimization design of the vaned diffusers is performed by the Response Surface Methodology (RSM). Through changing vane number and exit installation angle to construct candidate diffusers which are analyzed by CFD, sample data is then setup. The optimum design points with RSM based on different samples are almost in the same area and there is little error compared with the CFD result. It shows RSM can be able to fit the relation between design variant and response variant by less samples, and will become a power tool in the prediction of the performance and in the multi-variants optimization design in turbo-machinery field.
