UNSTEADY FREE CONVECTIVE FLOW PAST A MOVING VERTICAL CYLINDER WITH CONSTANT TEMPERATURE

R. K. Deka, A. Paul*

Abstract


An analysis is made for transient free convective flow about an infinite moving vertical circular cylinder with constant temperature. The governing boundary layer equations are first converted into a non-dimensional form. The exact solutions of the dimensionless governing linear boundary layer equations are obtained by Laplace transform technique. Graphical results for the velocity profile, temperature profile, skin friction, Nusselt number are discussed for various physical parametric values viz. Grashof number, Prandtl number and time.

Keywords


Heat transfer, Free convection, Moving vertical cylinder, Laplace transformation
