Magnetohydrodynamic flow of brinkman-type engine oil based MoS2-nanofluid in a rotating disk with hall effect

Abstract

Nanotechnology currently has an important role in reducing engine wear and improving fuel efficiency within engines using nanoparticles in engine oil. Therefore, the work reported in this paper, aims to investigate the magnetohydrodynamic (MHD) flow of Brinkman-type Engine Oil-based Molybdenum disulfide (MoS2) nanofluid (BEOBMN) in a rotating frame along with Hall effect and thermal radiation. The problem is modeled in terms of partial differential equations with physical initial and boundary conditions. The Laplace transform technique is used to evaluate the exact solutions for velocity and temperature profiles. Graphical results are obtained through a computational software Mathcad and discussed for various embedded parameters. The Skin-friction and Nusselt number are computed in the tabular form and it is noticed that the rate of heat transfer enhances 6.35% by adding MoS2 in engine oil which improved its lubrication.
