Simulation Analysis of Ejector Optimization for High Mass Entrainment under the Influence of Multiple Structural Parameters

As an energy-saving technology, the ejector is widely used in heating, aerospace, and chemical industry. The performance closely related to its structure, so structure of needs be optimized. In present study, single-factor optimization first carried out, main structural parameters affecting are screened out. Then, response surface method analyze combined effect multiple ejector, find out optimal flow field inside ejector. This study shows that, through numerical simulation, obtained by better than that or theoretically designed 35.4% higher Moreover, has high reliability, difference between simulation result prediction 0.96%.
