Numerical Simulation of Steam-water Ejector under Variable Condition

基于索克洛夫喷射器理论,对汽水喷射器的加热过程建立了数学模型,并编制了相应的计算程序,分析计算了工作蒸汽压力、引射水温度对喷射器结构参数设计的影响,以及喷射器运行时的最佳喷射系数与各参数的关系,提出了变工况运行的汽水喷射器的设计方法,为汽-水喷射器变工况的设计和运行提供了理论依据和分析方法.

On the basis of Sokoloff＇s ejector theory, a computational model of heating process by steam-water ejector is set up and its proceeding is programmed In addition, an analysis was conducted of the impact such parameters as the operating steam pressure, the temperature of jet flow on the designing of ejector, as well as the relation between those parameters and best entrainment ratio. The results offer a theoretical foundation and an analysis method for the design and operation of steam-water ejector on variable condition.
