Abstract

A new Low-Reynolds-Number "k-ε" turbulence model for prediction of heat and momentum transfer in turbulent shear layers developing under strong pressure gradient conditions is proposed. The model is a version of "k-ε" model recently proposed by Shih and Lumley, in which source terms of ε-equation have been modified to account for pressure gradient effects. This modification resulted in considerably improved prediction of strongly decelerated turbulent boundary layers.
Supplemented with algebraic stress relations and a transport equation for turbulent heat flux the present model, unlike existing "k-ε" models, is able to predict heat and momentum transfer in boundary layers developing under strong adverse pressure gradients.
