MHD TRANSIENT NANOFLUID FLOW AND HEAT TRANSFER FROM A MOVING VERTICAL CYLINDER WITH TEMPERATURE OSCILLATION
RÉSUMÉ
In the present study, the effects of magnetohydrodynamics (MHD) on the transient free convection flow of a viscous, electrically conducting, and incompressible nanofluid past a moving semi-infinite vertical cylinder with temperature oscillation is studied. The fluid is water-based nanofluid containing nanoparticles of copper (Cu) with a nanoparticle volume fraction range less than or equal to 0.04. The Tiwari-Das nanofluid model [Int. J. Heat Mass Transf., 50(9-10):2002-2018 (2007)] is employed. The dimensionless governing partial differential equations are solved by using a robust, well-tested, implicit finite difference method of Crank-Nicolson type. The obtained results are benchmarked with previously published work for special cases of the problem in order to access the accuracy of the numerical method and found to be in excellent agreement. In particular, the effect of significant parameters, such as magnetic parameter, phase angle, nanoparticle volume fraction, and thermal Grashof number, on the flow and heat transfer characteristics is discussed. The present simulations are relevant to magnetic nanomaterial thermal flow processing in the chemical engineering and metallurgy industries.
