Effect of thermal stratification on MHD free convection flow of a micropolar fluid over a stretching surface

This paper analyses the flow and heat transfer characteristics of free convection in the boundary layer flow of a micropolar fluid past a stretching surface with magnetic field, thermal stratification, and heat generation or absorption effects. A similarity transformation was employed to change the governing momentum, angular momentum, and energy partial differential equations into ordinary ones. Then the numerical solution of the problem is derived using the Runge-Kutta Gill method. The sheet is linearly stretched in the presence of a uniform free stream of constant velocity. Numerical results are shown in a tabular form and graphically for the velocity, angular velocity, and temperature as well as the skin-friction and wall heat transfer rate and discussed for various physical parametric values.
