Experimental and CFD analysis of nozzle position of subsonic ejector

Xilai ZHANG, Shiping JIN, Suyi HUANG, Guoqing TIAN

Frontiers in Energy 2009, Volume 3, Issue 2,   Pages 167-174 doi: 10.1007/s11708-009-0001-5

Abstract: The influence of nozzle position on the performance of an ejector was analyzed qualitatively with freeExperimental investigations and computational fluid dynamics (CFD) analysis of the nozzle position ofThe results show that there is an optimum nozzle position for the ejector.The ejecting coefficient reaches its maximum when the nozzle is positioned at the optimum and decreasesMoreover, the nozzle position of an ejector is not a fixed value, but is influenced greatly by the flow
