Bifurcation Behaviour in the Reverse—Flow Boundary Layer with Special Injection or Suction

Bifurcation solutions are numerically presented for reverse flow boundary layer equations with special suction/injection by utilizing similarity transformation and shooting technique.The results indicate that both superior solution and inferior solution are noticeable.The skin friction and shear stress for the superior solution decrease with the increases of the ratio of surface velocity to free stream velocity and suction/injection.The behaviour is opposite to that for the inferior solution.Both the skin frictions for the superior and inferior solutions decrease with increasing the power law parameter.The inferior solution approaches the superior solution with increasing the velocity ratio and suction/injection.When power law is unit and suction/injection is zero,the superior solution approaches the classical Blasius solution as the velocity ratio approaches zero.
