Assorted kerosene-based nanofluid across a dual-zone vertical annulus with electroosmosis
The goal of this numerical simulation is to visualize the electroosmotic flow of immiscible fluids through a porous medium in vertical annular microtubes. The inner region (Region I) is filled with an electrically conducting hybrid nanofluid while an electrically conducting Jeffrey fluid is flowing...

| description | The goal of this numerical simulation is to visualize the electroosmotic flow of immiscible fluids through a porous medium in vertical annular microtubes. The inner region (Region I) is filled with an electrically conducting hybrid nanofluid while an electrically conducting Jeffrey fluid is flowing in the second region (Region II). The chosen nanofluid is kerosene-based and the nanoparticles (Fe3O4-TiO2) are of a spherical shape. A strong zeta potential is taken into account and the electroosmotic velocity in the two layers is considered too. The annular microtubes are subjected to an external magnetic field and an electric field. The linked nonlinear governing equations with initial, interface and boundary conditions are solved using the finite difference method. The wall zeta potential and EDL thickness on the electric potential distribution, the velocity profile, the volumetric flow rate and the heat transfer are investigated versus the parameters under consideration. Graphs have been used to describe the numerical results of numerous emerging factors. It has been noticed that the temperature is the least for the clear fluid than the that of the non-clear one. Due to the fact that oil-based nanofluids are utilized to improve the stability and thermophysical characteristics of nanofluids when they are subjected to high temperatures, the proposed study presents a mathematical assessment that is sought to be useful in oil-based nanoflows' applications. |
