CFD analysis of Joule heating effect in a confined axi-symmetric swilling flow under the influence of axial magnetic field

Abstract

The effect of axial magnetic field along with axial temperature gradient, in a confined cylindrical cavity packed with incompressible electrical conducting fluid having a top rotating lid, has been investigated. Due to the presence of axial magnetic field, Joule heating effect is considered in this study. The governing parameters ranges are as follows: [Formula: see text], [Formula: see text] at Re[Formula: see text]1000, Pr[Formula: see text]0.015. It is found that the internal heat generation due to Joule heating in mixed convection is governed by interaction parameter and temperature gradient. However, the Joule heating effect has very less effect on primary flow in comparison to the secondary flow along the meridional plane.
