Numerical Simulation on Flow Structure of a Steam-jet Pump Influenced by Primary Nozzle Geometries
The aim of the paper is to reveal the flow structure and the mixing process of a steam-jet pump by using a computational fluid dynamics code FLUENT. Discusses the effect on a steam-jet pumps entrainment ratio when the throat diameter of the primary nozzle as well as the outlet diameter of the primary nozzle is varied. Analyzes the position of shock wave which will bring the steam-jet pumps performance a great loss. The performances of a steam-jet pump are studied by changing back pressures while the distance between primary nozzle outlet and mixing chamber inlet(DPM) is varied. The entrainment ratios of a steam-jet pump with different values of DPM and different back pressures are calculated.
