Abstract:

The numerical investigation of unsteady boundary layer slip flow and heat transfer of an incompressible Casson fluid on a vertically stretching sheet in presence of Suction and blowing. The above physical problem is represented in terms of Partial differential equations with boundary conditions. The suitable transformations are used to convert these governing partial differential to ordinary differential equations and then solved numerically by fourth order Runge- Kutta 4th order method with MAT LAB software. The impact of various governing parameters like Slip parameter (μ), Casson parameter (β), Heat generation and absorption coefficient (δ), Radiation parameter (Nr) on the velocity profile are discussed through graphs in detail. The study reveals that the variation of these parameters has erudite effect on velocity and temperature boundary layer thicknesses respectively. Also the variation of Skin friction coefficient and Heat transfer coefficient are studied numerically by increasing the values of parameters like slip parameter (μ), Unsteadiness parameter (A), and Casson parameter (β) etc. The graphs of these are plotted and discussed.
