Investigation of entropy generation on the mixed convective slip flow of nanofluids in an inclined channel with double dispersion effects

Aggregated studies on porous medium and double dispersion in nanofluid slip flow are important for the effective utilization of their striking thermophysical properties and extensive industrial applications. Particularly, the use of graphene based nanofluids in energy storage devices and as coolants has excellent applications in lithium-ion batteries. This investigation is one such computational study to explore the double dispersive flow in a porous medium between two inclined plates due to graphene oxide nanofluids and report the findings of the study. The flow is modelled including the impacts of thermal and solutal dispersion and thermophoretic diffusion and Brownian motion. The spectral method is used to solve the complex coupled nonlinear equations under convective conditions. The influence of implanted effects on skin friction, and entropy of the nanofluid are studied. A comparison table shows agreement between the literature and the obtained values. Also, the results obtained are graphed and discussed in detail along with entropy generation. This investigation reveals that the Hartmann number played significant role in enhancing the conductive heat transfer. Also, for 80% reduce in fluid suction, the skin friction drag increases by 14.99% and the Sherwood number increases by 11.86%. Furthermore, investigations have concluded that heat transmission is the primary contributor to entropy generation.
