Crecimiento de la capa límite interna originada por un cambio de contorno rugoso a liso en canales

Abstract

Internal boundary layer growth due to a change on roughness from rough to smooth in channels. In this paper an ecuation is stablished which defines the internal boundary layer growth due to a change on the roughness from rough to smooth, under conditions of torrent,ial flow in channels. Also a similitude law is defined for the velocity distribution inside the boundary layer and the shear stress downstream of the roughness change is devaluated.
