Item type: Item , Crecimiento de la capa límite interna originada por un cambio de contorno rugoso a liso en canales(1987) Isabel Florez; Maritza Ramírez; Julián AguirreInternal 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.Item type: Item , Distribución de velocidades originadas por el cambio de textura rugoso - liso en canales con escurrimiento supercrítico(1986) R. Fuentes; Julián Aguirre; Isabel Florez; Maritza RamírezAn experimental study has been achieved on the supercritical flow past a step change of boeoeon roughness: rough to smooth. The analysis of experimental data has allowed for the introduction of two dimensionless parameters; they define the evolution of the velocity profile past the change of roughness.
