A Computational Investigation of the Interaction of Pulses in Two-Pulse Jets
Authors:J. W. Anders  V. Magi
Affiliation:Purdue University , West Lafayette, Indiana, USA
Abstract:Large-eddy simulations (LES) and Reynolds-averaged Navier-Stokes (RANS) simulations of the interaction of the second pulse with the first pulse in a double-injection event are presented in this study. The opposing effects of the turbulence generated by the first pulse to accelerate mixing of the second pulse, and the residual bulk velocity from the first pulse to accelerate penetration of the second pulse are analyzed. The LES results show greater influence of the turbulence whereas the RANS results show greater influence of the bulk velocity.
