Abstract

This article is based on the impulsively started horizontal Riga plate in two dimensional unsteady Casson fluid flows with rotation. The plate starts abruptly from the rest relative to the rotating fluids moving with uniform acceleration in its plane. Numerical solutions are acquired by using explicit finite difference method and estimated results have been gained for various values of the Rotational parameter, modified Hartmann number, Prandtl number, Radiative parameter, Eckert number, Heat source parameter, Schmidt number, and the Soret number. Both the Compaq visual FORTRAN 6.6a and MATLAB R2015a tools have been used to find the numerical solutions and the graphical presentation. The Skin friction, Nusselt number and Sherwood number have been computed and the effects of some pertinent parameters on various distributions are discussed briefly and presented graphically.

Summary

Introduction

Casson fluid flows along the Riga plate create a new research area that plays a fundamental role in various industrial and engineering processes, such as MHD generators, thermal nuclear reactors, flow meters and the design of nuclear reactors. Raju et al [14] analyzed the heat source and chemical reaction effect on Casson fluid flow past an exponentially enterable stretching surface with thermal radiation and viscous dissipation. Rao and Sreenadh [15] investigated the steady two-dimensional MHD convective boundary layer Casson fluid flow over an exponentially inclined permeable stretching surface with thermal radiation and chemical reaction. Saidulu and Lakshmi [16] presented the heat and mass transfer boundary layer fluid flow of a non-Newtonian Casson fluid towards a porous stretching sheet with thermal radiation and suction. The Casson fluid flow with heat transfer and thermal radiation along a porous stretching surface is presented by Pramanik [17]. Ghulam Rasool et al [20] investigated the effect of a chemical reaction of nanofluids in the presence of Lorentz force and thermal radiation
