Effects of thermal radiation and electromagnetohydrodynamics on viscous nanofluid through a Riga plate

Abstract

Purpose

The purpose of this paper is to analyze theoretically the effects of thermal radiation with electrohydrodynamics through a Riga plate. An incompressible and irrotational fluid with constant density is taken into account. The governing flow problem is modeled with the help of linear momentum, thermal energy equation and nanoparticle concentration equation.

Design/methodology/approach

Numerical integration is used with the help of the shooting technique to examine the novel features of the velocity profile, temperature profile and nanoparticle concentration profile. The impact of all the emerging parameters is sketched with the help of graphs. The numerical values of local Nusselt number and Sherwood number are also presented.

Findings

The no-slip condition is considered for the present study. The effects of electromagnetohydrodynamics enhance the velocity profile while thermal radiation effects tend to raise the temperature profile. The present study depicts many interesting behaviors that warrant further study on Riga plates with different non-Newtonian fluid models. A comparison is also presented with the existing published results which confirms the validity of the presented methodology.

Originality/value

The results of this paper are new and original.
