摘要
设计了一套S弯扩压器轮廓模型的参数化生成程序,利用这套程序生成了13个模型,并进行了性能分析,得出了分叉截面位置、S弯段轴向长度、最大圆截面半径、最大圆截面位置四组参数对扩压器性能的影响规律。通过分析可知在分叉截面位置离进口近一点、S弯段轴向长度长一点、最大圆截面半径大一点、最大圆截面位置靠前一点的情况下,扩压器的性能较好。
This paper designs a program for parameterized-generating of S-Duct,creates 13 models by this program,analyzes the performance of each model,and gets the law of the influences of 4 parameters on the S-Duct as follow： when the divaricating position is near the inlet,the performance is better,that the longer length of the S-section,the greater radius of the maximum-section,and the nearer position after the inlet.
