![]() ![]() i.e., the product of the total area and the distance between free water surface and center of gravity of the contact area. A cylindrical wooden log of length L and radius r is floating on water (density d) completely submerge find the force on lower curved surface of the cylinder. The numerical investigations presented in terms of the graphs are interpreted with the help of underlying physics of the fluid flow and the consequences arising from the curved geometry. Here, is the moment of total area of contact about free water surface. In addition, the result for the plane surface is a special case of this study when the radius of curvature of the surface is sufficiently large. The dimensionless wall shear stress defined for this problem is greater than that of a linearly stretching curved surface, but becomes comparably less for a surface stretching with a power-law velocity. The numerical results depicts that the fluid velocity as well as the skin friction coefficient increases with the surface curvature, similar trend is also observed for the pressure. ![]() The resulting equations are solved numerically using shooting and Runge-Kutta methods. ![]() The governing boundary value problem is reduced into self-similar form using a new similarity transformation. In this paper, we present the boundary layer analysis of flow induced by rapidly stretching curved surface with exponential velocity. ![]()
