Abstract
Three-dimensional spatial DNS is used to investigate the near field dynamics of buoyant reactive jets. The physical problem is a fuel jet issuing vertically into an oxidant ambient environment. Simulations are performed for two cases in a corner configuration with side-wall boundaries: a corner-round reactive jet and a corner-square reactive jet with the same cross-sectional area on the nozzle plane. Buoyancy-induced large vortical structures evolve spatially in the flow field and transition to turbulence occurs downstream. Calculation of the mean flow properties shows that entrainment of the corner-round jet is stronger than that of the corner-square jet.
