Numerical Simulation on Rectangular Jet Vector Nozzle

Min Zhou

Abstract

A rectangular jet vector nozzle was designed based on the flow field characteristics.The assumption was presented that the jet was adopted in the nozzle to increase the speed of the main flow in the nozzle and form the exit vector angle.The 2D inner flow field in jet vector nozzle was simulated by the fluid calculation software FLUENT.The effects of the nozzle exit position on the aerodynamic parameters of flow field,thrust,exit flow direction and total pressure loss etc in the jet vector nozzle were analyzed.The effects of the nozzle exit position on the aerodynamic parameters of flow direction,thrust and total pressure loss etc with the asymmetric jet were also analyzed and the position of the second jet slot was confirmed
