Analytical study of swirler effects in annular propulsive nozzles
暂无分享,去创建一个
THIS paper presents an analytical performance prediction methodology for annular propulsive nozzles with swirl introduced ahead of the combustor that feeds the nozzle. The methodology is applied to investigate the effects of swirier design on nozzle performance. Four types of swirlers are investigated: free vortex, constant angle, forced vortex, and Rankine vortex swirlers. Discharge coefficients and specific impulses are presented. Contents
