NUMERICAL SIMULATION OF THERMAL RADIATION ON AN UNSTEADY MHD NANOFLUID FLOW OVER AN INFINITE VERTICAL FLAT PLATE WITH RAMPED TEMPERATURE

Abstract

The influence of magnetic field on unsteady magnetohydrodynamic (MHD) water-based nanofluid flow across an infinite flat plate with a ramped temperature gradient and radiative heat transfer in a porous material was investigated. Two forms of water-based nanofluids comprising silver and titanium dioxide were considered. The finite element technique was used to solve the governing partial differential equations, and the approximate results are provided. The temperature, velocities, rate of heat transfer, and shear stresses of nano-fluids at the plate are depicted graphically for a range of relevant parameter values. The velocity and temperature profiles upsurges with rising values of radiation factor, whilst the velocity diminishes for larger values of magnetic parameter. Engineering, glass manufacturing, paper manufacturing, and cardiovascular blood flow studies are just some of the industrial and medical applications for this kind of fluid flow model. Nanofluids are useful in engineering equipment where temperature and heat transfer owing to radiation fluctuate over time.
