Abstract

The behaviour of a turbulent forced buoyant plume sub- jected to uniform crossflow is investigated utilising Direct Numerical Simulation (DNS) employing a fourth-order finite difference scheme and third-order Adams-Bashforth temporal integration. The flow features are assessed phenomenologically in the statistically steady state obtained by averaging 1,200 instantaneous 3D fields. Preliminary results on the struc- ture of turbulent production and dissipation are shown in view of future discussions on LES modeling assumptions.
