Numerical study of the wall shear stress produced by the impingement of a plane turbulent jet on a plate

摘要: The present investigation has been carried out in the framework of numerical studies wall function influence on calculation shear stress. This stress is generated by action a normal plane impinging jet flat plate. Navier‐Stokes, continuity and energy equations are solved for two‐dimensional turbulent compressible flow using finite volume method. standard k‐e turbulence model used as closure model. To take into account external shape nozzle, quasi‐orthogonal curvilinear mesh used. For suitable stress, classical logarithmic law its generalized form results these calculations depend near grid. Therefore, this grid studied more specifically here. A hybrid proposed, which from simultaneous use one. gives distributions with less dependence validated through experimental data.
