Paper Title:
Investigation on the Mechanism of Energy Saving and Efficiency Enhancement for Fluid Ejector
  Abstract

Experiments were implemented on a prototype commercial liquid ejector to measure its hydraulic efficiency and the change of which along with a certain range of water flow rate variation was also recorded. Based on theoretical analysis and numerical simulation methods, we improved the ejector’s structure by modifying the suction part of it. Four ameliorated ejector structures, with increased pumping power and reduced flow resistance compared to the prototype, are proposed. Under the same working flow rate condition, flow field computations were conducted on the prototype and the four improved structures. The computational results show that the pumping power increases by 75.97%, the drag coefficient reduces 0.0908, the maximum turbulent energy dissipation rate decreases by 38.88% and the absolute value of the efficiency increases by 13.66%. The work validates the correctness of the theoretical analysis about the mechanism of energy-saving and efficiency enhancement for fluid ejector, and provides a more effective method to improve the performance of liquid ejector.
