Hybrid nanofluid flow over a vertical plate through porous medium in a conducting and chemically reacting field with radiation absorption and variable suction

Abstract

This research investigates the flow of an electrically conductive hybrid nanofluid across a porous plate that is in motion and experiencing temperature and velocity slip. In addition, the impacts of radiation absorption and variable suction are included. The heat transfer phenomena have been investigated using a hybrid nanofluid consisting of distilled water, brass, and cobalt. The behavior of the hybrid nanofluid is determined by the Tiwari-Das model. The graphs are drawn with the help of MATLAB software. It is noticed that compared to Cu3Zn2−TiO2 hybrid nanofluid, C−TiO2 with distilled water exhibits the optimum heat transfer by 5.72 % for fixed values of S and R. The temperature reaches at its maximum at y = 0.4520. Remarkably, the maximum improvement of 42.9547 % is noted for Ra=0.8,ϕ1=ϕ2=0.02,S=0.2,h2=0.5. The addition of brass and cobalt nanoparticles to a base fluid may considerably lower its operational temperature. The hybrid nanofluid composed of carbon-titanium oxide shows the greatest increase in heat transmission, but the hybrid nanofluid made of brass titanium-oxide indicates just a modest improvement. The buoyancy forces enhance the growth of both the momentum and thermal boundary layers. As the Cu3Zn2−Co hybrid nanofluid acts as a coolant, which can be used in the cooling of the battery.
