Abstract

In the present investigation, we propose a numerical simulation of two plane parallel TURBULENT jets. Several turbulence models were tested in the present work: the standard k   , the standard k   and the RSM models. A parametric study was also presented to pick up the nozzle SPACING and the VELOCITY RATIO effect on the merge and COMBINED POINT’ s axial and transverse positions. An investigation on the VELOCITY RATIO effect on the strong and weak jet spreading was also performed. It has been shown through the present investigation that the VELOCITY RATIO significantly affects the position of merge and COMBINED POINTs. Correlations between the merge and COMBINED POINTs position with respect to the nozzle SPACING and the VELOCITY RATIO are also provided. Results show that the increase in the VELOCITY RATIO moves the merge and COMBINED POINTs further upstream in the longitudinal direction while deflecting toward the strong jet in the transverse direction. The present numerical investigation allows us to conclude that when increasing the VELOCITY RATIO, the weak jet exercises some braking on the strong jet which decelerates its spread. On the other hand, the strong jet produces some acceleration on the weak jet, which enhances its spread.
