Effect of constant heat flux on forced convective micropolar fluid flow over a surface of another quiescent fluid

Due to the many applications of micropolar fluid such as blood, paint, body fluid, p olymers, c olloidal fluid and suspension fluid, it has become a prominent subject among the researchers. However, the characteristics of micropolar fluid flow over a surface of another quiescent fluid with heavier d...

Effect of constant heat flux on forced convective micropolar fluid flow over a surface of another quiescent fluid
description Due to the many applications of micropolar fluid such as blood, paint, body fluid, p olymers, c olloidal fluid and suspension fluid, it has become a prominent subject among the researchers. However, the characteristics of micropolar fluid flow over a surface of another quiescent fluid with heavier density of micropolar fluid under the effect of constant heat flux is still unknown. Therefore, the objective of the present work is to investigate numerically the forced convection of micropolar fluid flow over a su rface of an other qu iescent flu id usi ng constant heat flux boundary c ondition. In this study, the similarity transformation is used to reduce the boundary layer governing equations for mass, momentum, angular momentum and energy from partial differential equations to a system of nonlinear ordinary differential equations. This problem is solved numerically using shooting technique with Runge-Kutta-Gill method and implemented in Jupyter Notebook using Python 3 language.
