Ipsita Mandal, Swati Mukhopadhyay
Abstract
This paper aims to present the consequences of nonlinear convection on boundary layer flow of micropolar fluid over a non-isothermal exponentially stretching sheet. The influences of suction/blowing and heat source/sink are also considered. Using similarity transformations the governing partial differential equations are reduced to ordinary differential equations and these nonlinear equations are then solved numerically by converting the boundary value problem to an initial value problem with the help of shooting technique and Runge-Kutta method. The results are discussed through graphical representations providing physical interpretations as far as practicable. It is found that both fluid velocity and angular velocity increase with the rise in material parameter but the temperature decreases in this case. Fluid velocity increases but the angular velocity and temperature both decrease with the rise in mixed convection parameter and also with the nonlinear convection parameter.
