Soft Computing Approach to Solve Effect of Variable Viscosity and Thermal Diffusivity on Unsteady Porous Stretching Sheet

Abstract: The present communication explores the unsteady boundary layer flow on a porous stretching sheet. The thermal diffusivity and viscosity are assumed to vary as linear function of temperature. Using the stream function; the governing partial differential equations are converted into ordinary differential equations. The obtained boundary value problem is converted into equivalent initial value problem using continuous genetic algorithm and solved by Runge-Kutta Fehlberg method. To carry out analysis the results are depicted in the form of figures.
