摘要

An experimental investigation for the aerodynamic effects of fluidic injection in a two-dimensional, convergent-divergent (2DCD) nozzle has been conducted. Simulations were performed at static conditions of a single fluidic injection port with variable injection angles (60°, 90° and 120°) at a relative position of x/x_l=0.688, with the scheduled nozzle pressure ratios (NPR, from 4.5 to 13.89) and secondary to primary total pressure ratios(SPR) from 0.4 to 1.0. Results indicated a pressure rise on the nozzle wall centerline. It validated that the nozzle thrust vectoring angle and thrust coefficient change with different NPRs, SPRs and injection angles.
