Navier-Stokes Mixed Convection Flow Visco-elastic Fluid Boundary Layer Theory


Abstract

Mixed convection flow is the combination between free convection flow and forced convection flow. In this research, the pressure and buoyancy forces are significant. The governing equations are taken from Navier-Stokes equation that includes continuity, momentum, and energy equations. These equations are obtained from Boussinesq and boundary layer approximations. These non-dimensional equations are then transformed into non-dimensional equations to make easy in numerical processes. Further, these non-dimensional equations are transformed into non-similar equations and solved numerically using the finite difference method. The numerical results are analyzed the effect of Prandtl parameter ( ) and visco-elastic parameter ( ) to velocity profile ( ) and temperature profile ( ). The temperature profile decreases and the velocity profile decreases when the prandtl parameter increases. Meanwhile, the temperature profile increases and the velocity profile decreases when the visco-elastic parameter increases.
