BOUNDARY-LAYER FLOW AND HEAT-TRANSFER ON A CONTINUOUS MOVING WAVY SURFACE

The effect of spatially stationary surface waves on the forced convect ion induced by a moving surface in an otherwise quiescent fluid is exa mined. We consider the boundary layer regime where the Reynolds number Re is very large, and assume that the surface waves have 0(1) amplitu de and wavelength. The boundary layer approximation is valid and the r esulting parabolic equations are solved using the Keller-box scheme. D etailed results for the local skin-friction coefficient are presented, as are results for the local Nusselt number for both the cases of a c onstant wall temperature and a constant wall heat flux.
