## SIMULATION OF AN IMPINGING JET ISSUED INTO A CROSS FLOW WITH RANS AND LES METHODS
## AbstractSimulation of the fluid flow and heat transfer of an impinging axi-symmetric jet exiting perpendicular into a cross flow is carried out. Basicly, two methods are employed to model the physics of turbulence: one is by solving the Reynolds averaged Navier Stokes equations (RANS); the other is by the large eddy simulation (LES). In the RANS method, a linear eddy viscosity model (AKN, Abe et al., 1994), an explicit algebraic stress model (EASM, Rokni 2000), and a V2F model Durbin (1995) are employed to close the time averaged momentum equations. The nozzle-to-wall distance (H) is kept at four nozzle diameters (D), while the span-wise width of the channel is 8D. Three ratios (M) of cross flow to jet velocity are considered (0, 0.1, 0.2) for a jet Reynolds number ( |
