Magnetohydrodynamic Flow of Water Base Nano Fluid and Non-Newtonian Fluids Over a Permeable Stretching Surface

摘要

The present study, we have investigated MHD flow for water base nano fluid and non-Newtonian fluids over a permeable surface. We have considered the following non-Newtonian fluid and water base nano fluid such as Maxwell fluid, Williamson fluid, Ag-water nano-fluid and Al2O3-waternano-fluid and TiO2-water nano-fluid in the presence of radiation and transverse magnetic field. The governing PDEs are changed into higher order coupled ODEs. We have solved by bvp4c solver with Matlab. We discussed the various physical parameters such as Maxwell fluid parameter(λ), Williamson fluid parameter (We), Ag-water nano fluid, Al2O3-water nano-fluid and TiO2-water nanofluid, magnetic parameter (M), Eckert number (Ec), radiation parameter (R) and suction/injection parameter (S) onvelocity and heat profile is discussed and depicted graphically. We observer that to mention the f′ and  profiles that the nano-fluids are extremely affected by magnetic field parameter (M) compared with non-Newtonian. Increases the value of magnetic fieldparameter than silverwater nano fluid higher influence to other nano fluid such as Aluminium-water and Tin-water nano fluid whereas in non-Newtonian, Maxwell fluid higher influence of Williamson fluid.
