Calculations of the effects of high free stream turbulence (FST) on the transport of momentum and heat in a flat plate turbulent boundary layer are presented. Four well known low Reynolds number k-ε models namely Launder-Sharma, K.-Y.Chien, Lam-Bremhorst and Jones-Launder were used in order to investigate specifically their prediction capabilities under high FST conditions (initial FST intensity. Tui>5).These models were implemented n computer code TEXSTAN,a partial differential equation solver which solves steady flow boundary layer equations. Firstly, these models were compared with empirical data and standard correlations to test how they predicted very low FST (Tui=1) cases.
