Abstract : Interactions of multiple jets have several industrial applications like jet mixing in rocket engine and in combustion chambers. Non-premixed (diffusion) flame is used in many applications owing to its stability. The present study considers three-dimensional simulation of three separated oxy-methane jets which shows that combustion has a prominent impact on their velocity distribution. The radial distributions of longitudinal velocity at different axial locations have been examined. Comparison has been done on reactive and non-reactive jets. Velocity decay for reactive jets is found to be slower relative to non-reactive jets. Turbulent intensity is higher in non-reactive jets which causes faster spreading. The temperature profile shows that the peak temperature does not exist on the centerline plane but at some offset height from the oxy-fuel centerline plane. The study has been carried out for different jet inlet temperatures. Increase in inlet temperature of reactant leads to a faster velocity decay. © Springer Nature Singapore Pte Ltd. 2019.
