Abstract

The effects of the thermodynamic analysis of the MHD nanofluid flow with horizontal annulus with internal cylindrical rotation are numerically studied in this article. The effects of viscous heating(or dissipation) and ohmic heating are also considered. The momentum, thermal and solutal equations are numerically solved by the RK4 method together with the shooting technique, subject to the associated boundary conditions. The response of various relevant parameters on flow, heat and mass transfer, entropy and bejan numbers are investigated. Results demonstrate that the velocity diminishes with the expansion of Lorentz forces however increments with the increment of Reynolds number. The Bejan number decelerates with the expansion of the Brinkman number and the Brownian parameter
