Mass transfer effects on the threedimensional secondorder boundary layer flow at the stagnation point of blunt bodies
Abstract
Solutions are presented to the secondorder boundary layer equations to show the effects of mass transfer on wall shear and heat transfer in the case of an incompressible threedimensional stagnation point flow. On impermeable walls, longitudinal curvature reduces the short crosssectional component of the shear stress near the general stagnation point, whereas the long crosssectional component is increased; heat transfer is reduced. Transverse curvature augments the short and reduces the long crosssectional components of shear stress, while increasing heat transfer. These tendencies are intensified by blowing, due to artificial thickening of the boundary layer; here secondorder effects may prevail over classical theory. Suction reduces boundary layer thickness; at large suction rates secondorder effects are small compared to classical results.
