Significance of Coriolis force, volume fraction, and heat source/sink on the dynamics of water conveying 47 nm alumina nanoparticles over a uniform surface

Abstract With a major emphasis on the applications of water conveying 47nm alumina nanoparticles in mechanical and biomedical industries, little is known on the variation of not only the transport phenomena (i.e. velocity), but also the concentration and temperature distribution across the domain when increasing Coriolis force, heat source/sink, and volume fraction are apparent. The relevant body forces were added to the Navier-Stokes equations to model the transport phenomenon over an object with uniform thickness. Appropriate similarity transformation for non-dimensionalization and parametrization of the partial differential equations was considered. The numerical solution of the corresponding ordinary differential equation (BVP) was derived with the aid of three-stage Lobatto IIIa collocation formula embedded in MATLAB package as bvp4c , and Shooting techniques together with fourth-order Runge-Kutta integration scheme ( Sh-4RK ) and natural neighbor of data grinding method. It was found that Coriolis force and heat source/sink strongly affect not only the motion but also the temperature distribution and nanofluid concentration. Enhancement of volume fraction of tiny alumina particles is a yardstick for boosting not only the Nusselt number inversely proportional to the rate at which heat transfer occurs at the wall but also shear stress at the wall in x − and y − directions. Heat source affects the formation of friction formed at the wall during the dynamics of nanofluids subject to Coriolis force.
