Abstract
The objective of this paper is to analyze the combined effects of thermal radiation and magnetic field on three different types of channel flow of Brinkman type nanoliquids. Two types of carbon nanotubes namely single-walled carbon nanotubes (SWCNTs) and multi-walled carbon nanotubes (MWCNTs) are suspended in three different base fluids (Water, Kerosene-oil and Engine-oil). Based on Xue model, the thermo-physical properties of each base fluids and nanoparticles are incorporated in the form of thermal conductivity, density and specific heat. The problem is modelled in terms of partial differential with imposed boundary conditions. Analytical solutions via perturbation method are obtained for velocity and temperature, plotted graphically for all three cases and discussed for embedded flow parameters. The shear stress and the rate of heat transfer are also computed in tabular forms. Results showed that velocity of MWCNTs is greater than SWCNTs. Velocity decreases with increasing Brinkman type nanoliquids and radiation parameters.
