Abstract

The spreading features of five supersonic jets, in the configuration of one central bigger jet surrounded by four smaller equi-distant peripheral jets have been studied numerically and experimentally for different Mach numbers and spacing ratios. The computed values are in good agreement with the experimental results. The jets maintain their individual behavior up to twelve diameters and thereafter they merge to form a single jet. For smaller spacing ratio and lower Mach number, the merger occurs earlier compared to higher spacing ratio and larger Mach number. The mass flux rate increases with the spacing ratio. The Reynolds shear stress and turbulent kinetic energy are higher for under expanded jets than for correctly expanded jets and over expanded jets.
