| Abstract | Experimental data of horizontal fluid velocity in the codirected wave current system were obtained by Brevik and Aas (1979), and Brevik (1979) for
smooth and rough bed respectively. In this present study, the above experimental data are analyzed to develop velocity profiles, shear stress profiles, friction factors and eddy viscosities for both steady and unsteady components. The logarithmic form can fit both steady and unsteady components of velocity
profile well. For current and wave velocity having approximately the same
magnitudes, the unsteady shear stress is found to be predominant and the
friction factor of wave-current system is about 2-5 times greater than that of pure wave. Eddy viscosity analyzed by using an analytical derivation of
shear stress is found to be a function of wave period and the wave boundary layer in the presence of current. |
