Abstract
The primary aim of the present work is to simulate the laminar-turbulent transition of confined planar jet opening in a rectangular channel using Large Eddy Simulation (LES), as implemented in OpenFOAM. The sub grid scale turbulence was captured by the Smagorinsky model with Van Driest damping function. Simulations were performed on resolved grids and for different Reynold numbers. Q-criterion and the components of the Reynolds stress tensor were determined after the simulations were initially stabilized. Mean velocity profile at the midplane of the channel was compared with the analytical result of the damped flow. Strength of the entrained vortex was determined. Pressure fluctuations at the jet inlet were analysed. Transition was observed at channel-based Reynolds number of lower than 1200.
