一、引言直到现在,风机、压缩机方面文献,在论及叶轮最佳进口设计时,一直沿用这样的观点:最佳的叶轮进口设计,是使气流进入气流的相对速度W_1最小。并由此得出W_1最小时最佳叶片进口直径。同时也得出最佳叶片
I. INTRODUCTION Until now, literature on fans and compressors has always followed the view that the best impeller inlet design is to minimize the relative velocity W_1 of the airflow into the airflow. And the best blade inlet diameter from W_1 is obtained. Also come to the best leaves
