Entrance Effects of Blood Model Casson Fluid in the Concentric Rings with Inner Ring Rotation

Abstract

This research article analyzes the entrance effects in concentric rings with rotation of inner ring for the blood model Casson non-Newtonian fluid. The investigation is done with the assumption that, the inner ring rotates with a constant velocity along angular direction also the outer ring is at rest. The finite difference technique was applied to find the velocity profiles, variation of pressure in the radial coordinate direction. Calculation has been done for different annular gap values and Casson number. The compared results for different special cases was made and observed to be concordant
