A new Boussinesq-type model describing periodic wave propagation over a constant depth has been developed for the cases where the effects of a turbulent boundary layer are significant. In this paper, the eddy viscosity model is employed in the turbulent boundary layer and is further approximated as a linear function of the distance measured from the seafloor. The boundary-layer velocities are c...

A parametric investigation of the influence a small cylinder on laminar separated boundary layer over NACA0012 wing is performed using numerical simulations. The (γ - Reθ,t) steady RANS transitional model first validated in capturing separation baseline suction surface. effects three rod diameter ratios (d/c = 0.67%, 1.33% and 2%) bubble aerodynamic performances were examined. qualitative analy...

The rotating-flow boundary layer is a special case of the more general threedimensional boundary layer in which the pressure gradient imposed by the outer flow (above the boundary layer) is not in the same direction as the outer flow. The rotating-flow boundary layer thus has motion that is transverse to the streamlines of the outer flow, that is, there is a secondary circulation to the primary...
