Dynamics of Ohmic heating and aligned magnetic field on a nanofluid flow between two coaxial cylinders with rotation effect

Abstract

The flow and thermal transfer of nanoliquid (Water + Fe3O4) between two circular parallel cylinders, one of which is at rest and the other rotating, are examined in this article using an aligned magnetic field and Ohmic heating effects. The improvement of the thermal field caused by the interfacial nanolayer is demonstrated. The resulting set of ordinary nonlinear differential equations is handled by using the Keller–Box technique. Comparable outcomes for base fluid (water) and nanoliquid are obtained and discussed. The impact of the magnetic parameter, Grashof number, Brinkman factor, and radiation components on nondimension velocity and temperature are analyzed and represented graphically. The magnetic parameter and the Brinkman number are found to be proportional to the temperature distribution.
