Effects of Multiple Constrictions on Micropolar Fluid Flow through a Channel of Non-Uniform Cross-Section

摘要

The flow of an incompressible micropolar fluid in a two dimensional channel with non-uniform cross- section and multiple stenoses has been investigated. Assuming the stenoses to be mild, the flow equations have been linearised and the expressions for resistive impedance and shear stress acting at the wall have been derived. The effects of pertinent parameters on these flow variables have been studied. It is found that the resistance to the flow increases with micropolar parameter and the number of stenoses. However, the shear stress acting on the wall decreases with micropolar parameter.
