Five versions of low Reynolds number k-ε models including the original one have been tested against the DNS data for ID oscillatory boundary layers; one with sinusoidal and another with flat-crested free-stream velocity variation. The comparison has been made for the cross-stream velocity, turbulent kinetic energy, Reynolds stress, and wall shear stress. It is found that the original model is superior to the more recent models by virtue of its numerically desirable boundary conditions and accuracy of prediction for mean flow properties. A brief description about the wall-limiting behavior of important turbulent quantities is presented to recognize physically correct k-ε models.
