Abstract
A priori test using the LES data base is carried out to evaluate the Algebraic stress model (ASM), the WET model and the linear eddy viscosity model. The accuracy and relative performance of their turbulent heat flux models are carefully examined in both plane wall jet and impinging jet regions. The ASM gives a good result by counterbalancing them though the modeling pressure-temperature gradient term and the algebraic approximation is not so efficient. The WET model require the use of appropriate wall damping function to preciously predict wall shear flow.
