Abstract :
A 3D numerical simulation using large eddy simulation (LES) method is performed for a submerged turbulent
water slot jet impinging normally on a flat plate with a nozzle-to-plate distance of 10 jet width and a
Reynolds number of 16000 and the results are compared with the existing experimental data. The numerical
platform is an open source CFD code based on the field operation and manipulation C++ class library for
continuum mechanics (OpenFOAM) and is used to simulate the flow and represent the mean and
instantaneous flow field characteristics. Also, simulations are performed with two different subgrid-scale
(SGS) models, one-equation based subgrid-scale model and localized dynamic smagorinsky model.
Evaluating the different subgrid-scale (SGS) models, a priori and a posteriori test is done. Comparison
between results obtained using the SGS models and experimental data shows that the simulation results using
localized dynamic Smagorinsky model are more compatible with the experimental data compared with those
that obtained from the kinetic energy one-equation model especially in regions close to the impingement wall
and in free jet region.
