| Abstract: | 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 vari... |
