Description

As for jet noise reduction of an air micro-injector with divergent nozzle, dimples shape in the inner surface of divergent nozzle is proposed, in the paper, the jet noise reduction effect of dimples shape is numerically confirmed at delivery pressure 1.33 atm. and 2.0 atm. (fully expanded jet Mach number 0.65 and 1.05), using Ffows Williams and Hawkings (FW-H) method base on time-accurate solutions of Large-Eddy Simulation (LES). In addition, the influence of dimples nozzle on the jet flow field is numerically investigated. (paper)
