EFFECTS OF BROWNIAN MOTION AND THERMOPHORESIS VARIATION ON MHD NANOFLUID FLOW IN A CONCENTRATED PARABOLIC THERMAL SOLAR COLLECTOR

Abstract: This research paper investigates the effects of Thermophoresis and Brownian motion parameter variation on heat and mass transfer on MHD nanofluid flow in a parabolic thermal solar collector. The effect of laminar flow which is occasioned by a variation in the Brownian motion and Thermophoresis parameter over a parabolic shaped photovoltaic surface has been investigated numerically. The model used for the nanofluid flow incorporates the effects of Brownian motion and thermophoresis parameter variation with thermal variation due to solar radiation in the presence of an induced magnetic field cutting perpendicular across the flow. The governing equations of the MHD fluid flow are presented and solved using the finite element method. The results show that increasing the Thermophoresis  and Brownian motion parameters  lead to an increase in heat transfer and a decrease in mass transfer. Similarly, an increase in the Peclet number  favors mass transfer but impairs heat transfer. A comparison of the results with existing literature has been done and a remarkable agreement established.
