Abstract
In order to study the influence of jet angle on the supersonic inflow,by using the FLUENT software,the numerical simulation of injection angles of 30°,60°,90°,120°,135° and 150° was conducted with the second-order central difference for the viscosity term,second order upwind scheme for the advection term and the standard double-equation k-ε for the turbulence model. It is found in the research that with the increase of injection angle,the separation range of the flat bottom area is expanded, the bow shock wave of symmetry plane is enhanced and the total pressure loss is increased,and the mixing efficiency is best when the injection angle is 150°.关键词
