Mixed Convection Flow of a Micropolar Fluid on a Moving Heated Horizontal Plate

Abstract

Steady laminar boundary layer flow and heat transfer of a micropolar fluid over a heated isothermal horizontal plate moving in a flowing stream has been studied in this paper. The cases corresponding to the isothermal horizontal plate moving in the same (parallel) or in the opposite (reverse) direction to the free stream are considered. Similarity and nonsimilarity equations of six special systems are reduced readily from universal formulation. The governing momentum, angular momentum, and energy equations have been solved numerically. The effects of buoyancy and relative velocity on the flow and temperature fields including surface friction and heat transfer rate are presented for a plate moving in parallel or reversely to the free stream. It is observed that micropolar fluids display drag reduction when compared to Newtonian fluids.

Numerical simulation of micropolar fluid flow along a flat plate with wall conduction and buoyancy effects

“…The problem of mixed convection heat transfer in a micropolar fluid flow has been extensively researched by a number of investigators [12][13][14][15]. More recently, Mohammadien et al [16] investigated the effects of buoyancy on the mixed convection flow of micropolar fluids for the case of a moving heated horizontal plate. Siddheshwar and Sri Krishna [17] applied the Fourier series expansion method to the linear and non-linear analysis of convection in a micropolar fluid occupying a porous medium.…”
