Transient Rotational Flow of Radiative Nanofluids over an Impermeable Riga Plate with Variable Properties

Abstract:

The present investigation imparts an analysis on the effect of time-varying rotation and thermal radiation on diversified nanofluids possessing water as base fluid and Magnetite , Cupper Oxide (CuO), and Titania (TiO) as nanoparticles. Variable fluid properties such as variable viscosity and variable thermal conductivity are taken into consideration. Ensuring implementation, Successive Relaxation method is the instrumental in obtaining the most appropriate numerical solution of the transformed differential equations. One of the marvel outcomes of the current study is that moderate rotation reduces the axial and transverse wall shear stresses and augments the heat transfer rate while higher rotation exhibits the reverse trend for Water-Magnetite, Water-Cupper Oxide, Water-Titania nanofluids.
