Similarity Solution and Heat Transfer Characteristics for a Class of Nonlinear Convection-Diffusion Equation with Initial Value Conditions

الملخص EN

A class of nonlinear convection-diffusion equation is studied in this paper.

The partial differential equation is converted into nonlinear ordinary differential equation by introducing a similarity transformation.

The asymptotic analytical solutions are obtained by using double-parameter transformation perturbation expansion method (DPTPEM).

The influences of convection functional coefficient k(z) and power law index n on the heat transport characteristics are discussed and shown graphically.

The comparison with the numerical results is presented and it is found to be in excellent agreement.

The method and technique used in this paper have the significance in studying other engineering problems.
