摘要
利用透平机械欧拉方程和经典的变分原理，推导出了内燃机冷却风扇沿径向气流参数优化设计的数学模型，建立了风扇叶片扭曲规律优化设计的数学方法．应用该方法对６１０２汽油机冷却风扇进行了优化设计。
This paper deals with the solid discharge properties of a gas solid injector at different inlet suction vacuums and a fixed diffusor outlet pressureatmospheric pressure. Four particulate solids of 325 Mesh talc, FCC catalyst, coal ash and MBS resin are used to examine the effects of powder properties on solid discharge flow rates of the injector. The tests show that the solid/gas mass flow ratio varies linearly with the inlet suction vacuums and also differs in powder properties.
