Radiation and Magneticfield effects on Unsteady Natural Convection Flow of a Nanofluid Past an Infinite Vertical Plate with Heat Source

P. Mohan Krishna, V. Sugunamma, N. Sandeep


In this study, we analyze the effects of thermal radiation and magnetic field on unsteady natural convective flow of a nanofluid past an impulsively started infinite vertical plate in presence of heat source. The nanofluid contains Copper, Nikel, Zinc Oxide nanoparticles with water as base fluid. The partial differential equations governing the flow are solved numerically by Laplace Transform Technique. The effects of various parameters on velocity and temperature profiles examined and presented graphically .It is found that the increase in magnetic field causes the decrease in fluid velocity, fluid velocity and temperature profiles are more influenced by Radiation, Heat source and Volume fraction of the nanoparticles. Shape of nanoparticles does nots hows effect on the velocity of the fluid.

Key Words: Heat transfer, Nanofluids, Thermal radiation, MHD, Heat source, Volume fraction.
