1.Start from the Navier–Stokes equations and derive the governing equations in Cartesian coordinates for low Reynolds number flow, referred to as creep flow.
2.Make appropriate assumptions and drive the two-dimensional boundarylayer equations for flow over a flat plate in Cartesian coordinates.
3.Specified surface concentration. The surface concentration is specified as a constant concentration or a function of space and time, i.e. C ¼ CSðx~, tÞ on the surface S ð where CSðx~, tÞ is a function of time and position or it could be a constant surface concentration, CS.
