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.
•Flow of nanofluid by a Riga plate is formulated.•Brownian motion and thermophoresis are accounted.•Riga plate has variable thickness.•Convective condition of temperature at Riga plate is utilized.•Newly developed mass flux condition at Riga plate is implemented.
