Abstract: Three versions of low Reynolds number k-ε model have been tested against the DNS data for a transitional oscillatory boundary layer. The original model is observed to predict the transitional characteristics better than the other versions. However, the later versions perform better by virtue of the magnitude of velocity, turbulent kinetic energy and bottom shear stress.
