A New Numerical Approach for the Laminar Boundary Layer Flow and Heat Transfer along a Stretching Cylinder Embedded in a Porous Medium with Variable Thermal Conductivity

Abstract EN

The study presents an axisymmetric laminar boundary layer flow of a viscous incompressible fluid and heat transfer over a stretching cylinder embedded in a porous medium.

A suitable similarity transformation is employed to transform the partial differential equations corresponding to the momentum and heat equations into nonlinear ordinary differential equations.

The resultant ordinary differential equations are then solved using a successive relaxation method (SRM).

The effects of significant parameters on the velocity and temperature profiles have been analyzed graphically.

The obtained results are also compared with previously published results in some special cases and were found to be in excellent agreement.

The skin friction as well as the heat transfer rate at the surface are increased as the values of the curvature parameter increase.
