摘要(Abstract):

本文研究高温喷射器的近似理论计算问题;建立了常温气流及高温气流的两股流体的动量方程和能量方程。根据优化条件决定最佳面积比和混合室的压力值以及采用渐近法得到混合室的温度及引射系数。并讨论了喷射器端口阻力特性对喷射器性能的影响
This paper reviews an approximate calculation and its application of elevated temperature ejector. The optimum of area ratio and the pressure of the chamber of the ejector are derived from optimal conditions. According to asymptotic approach the temperrature of the mixing chamber and the entraining coefficient can be obtained. The effect of fluidic port charact ristics of the ejector on its operating properties are also disscused.
