Using intelligent hot line anemometer, single& monoclinal wire omnidirectional rotating sampling technique, measurement should be carried out to the internal flow field of centrifugal compressor vaneless diffuser under the seven kinds of width. 利用智能型热线风速仪,采用单直丝和单斜丝联合多方位旋转采样技术[1],在7种宽度下对离心压缩机无叶扩压器内部流场进行了测量。
For matching turbine work condition, designed a diffuser that transformed square to round, chose central line and shape changed method, defined diffuser expanding angle. 给出了一种亚音速方转圆扩压器的设计方法,并对中心线形状、型面变化规律和扩张角等进行了选择和说明。
A diffuser design method is presented, and the way of how to choose the center line, section shape and diffuser expand angle are demonstrated. 给出了既可调节喉部面积,又可以与发动机连接的跨声速扩压器设计方法,并对选择中心线形状、截面形状变化规律和扩张角的选取原则进行了说明。
