Abstract: A new assessment is made of two-equation (k-ε) and one-equation (k-l) turbulence models in oscillatory flow. The turbulence models are compared with the data of Jensen, Sumer and Fredsoe[1]. An attempt is made to quantify the uncertainties in the Reynolds shear stress measurements. The results show that the k-εmodel performs well, and considerably better than the k-l model.
