In this paper, the analysis of two dimensional viscous incompressible flow around bodies with multiple industrial applications, is presented. Both of boundary layer flow and potential flow have been analysed repeatedly and in this way, the major parameters of flow are calculated. Laminar and turbulent boundary layer flow are solved with the aid of an virtual flow normal to the surface of the body as boundary conditions. The flow around the body has been made by combining the uniform potential flow and distribution of potential source and sink and vortex on the surface of body and constantly powered vortex on the separation streamline. The rotational flow in wake region is also made. With a development of computational program, the numerical method is applied in which, the power and situation of distributed singularities are obtained. Considering wake length and minimum pressure coefficient from empirical data, the shape of streamlines and consequently boundary layer around the body have been obtained. Also, distribution of pressure and velocity and curve of streamline beginning from separation point, have been calculated and compared with empirical values.
