Abstract
Impinging jets flow is a complex turbulence flow and has strong heat transport capacity, which was generally used in civil aviation area such like wing anti-ice, turbine blade cooling, etc. In this paper impinging jets flow was simulated using the multiscale turbulence model based on the variable interval time average method. The numerical method used in this simulation is a structured staggered mesh scheme. The computational result shows that the multiscale turbulence model can successfully simulate flow and heat transfer characteristics of impinging jets from wall surface to potential core area. The Nusselt number also agree better with experiments than that of the standard k-ω model.
