Thermodynamic Analysis for a Cross Diffusive Magnetized Couple Stress Fluid in Horizontal Inner Rotating Cylinder


Volume: 1 Issue: 1
Year of Publication: 2019
Authors: S. Shilpa, G. Nagaraju, Anjanna Matta



Abstract

The current study analyzes the rate of entropy generation in the MHD flow of couple stress fluid through the horizontal inner rotating cylinder is implemented by using the thermodynamics second law. For the governing equations an analytical result is evaluated using the theory of Modified Bessels functions. The influence of couple stress parameter, Magnetic parameter, Brinkman number, Soret and Dufour number, Temperature and concentration difference parameters on the velocity, temperature distribution, entropy generation rate and Bejan number are investigated and the results were presented graphically. It is concluded that, the solutal diffusivity has a major conclusion on the rate of entropy generation and it is not an irreversible process of heat in the flow of a couple stress fluid.
