Abstract

Flow characteristics over a rough flat plate are studied through an experiment, carried out in the laboratory using a low speed wind tunnel. Velocity reading are taken at equal intervals over the flat plate (wood surface glued with a 40 grade emery paper) over a free stream velocity of 12.3m/s. Velocity profiles are plotted at different sections along the longitudinal length, which ultimately give the boundary layer over that section. The boundary layer thickness ranges from 3.2mm to 50.2mm. The boundary layer growth gives a brief idea of fluid flow over a flat surface. Comparison between four rough flat plates gives a better understanding of boundary layer. Analysis of boundary layer gives a better idea for design of aerodynamic objects.
