diffuser efficiency

Some special requirements must be considered in rocket design, such as the flight Mach number during sampling flight, the flow coefficient and aerodynamic characteristic of sampling diffuser, the efficiency of filter material and others.

该火箭的设计需要考虑取样飞行马赫数、取样扩压器的流量系数和气动特性、取样过滤材料的效率等特殊要求。

A optimal diffuser stagger angle should exist at a fixed mass flow rate to make the diffuser have highest efficiency;

在给定的流量工况下，应存在一个最佳的进口安装角，使得扩压器效率最高；

The results, which obtained by using radial diffuser, show that due to the high loss through the diffuser, the efficiency of the liquid hydrogen pump is lower.

采用径向导叶的液氢泵的试验结果表明，导叶损失大，导致液氢泵效率低。

Opal diffuser with 70 % optical efficiency provides wide luminance dust and moisture proof easy to clean.

透光板采用进口乳白板,防尘,防潮,晚清洁,透光率为70%,照度面广.
