Flow of nanofluid due to convectively heated Riga plate with variable thickness

Abstract

This article is concerned with the characteristics of boundary layer flow of nanofluid induced by a Riga plate with variable thickness. Properties of heat transfer are studied with convective boundary conditions and heat generation/absorption. Riga plate is distinguished as electromagnetic actuator comprises of permanent magnets and a spanwise aligned array of alternating electrodes mounted on a plane surface. Nanoparticle flux is assumed zero at the surface. Appropriate transformations are employed to develop the non-dimensionalized governing equations. Impacts of velocity, temperature and nanoparticles volume fraction distributions are described through graphs corresponding to various pertinent parameters. It is noted that velocity distribution shows decreasing behavior for higher values of modified Hartman number.
