Laminar Boundary Layers over a Rotating Cone with Uniform Suction or Injection.

Abstract

The problems of axially symmetric boundary layer flow over a rotating cone with uniform suction or injection in forced flow have been theoretically investigated. The nonlinear partial differential equations along a cone are transformed into ordinary differential ones by means of the difference-differential method. The solutions of the resulting equations are expressed in a form of integral equations, and the equations are numerically calculated by iterative numerical procedures. The results indicated that the axial and tangential velocity profile and the temperature profile shrink as the suction or injection parameter s increases. The drag and torque coefficient and the heat transfer coefficient increase as s increases.
