摘　　要：本文结合喷射器的特性曲线方程,根据喷射器结构尺寸的计算方法编程,计算出初始条件下喷射器的具体尺寸,并根据计算结果建立喷射器模型,依次改变工作流体、引射流体和出口压力,运用Fluent模拟实际运行过程中工况改变对喷射器性能的影响。It is programmed to calculate the specific dimension according to the calculation method of the ejector structure size under initial conditions combined with the characteristic curve equation. Then the ejector model is established, and the pressure of the working fluid, the fluid ejector and the outlet fluid are changed in turn to simulate the influence on the performance of ejector of variable conditions in the actual operating process using Fluent.
