Three-dimensional hydromagnetic hybrid nanoliquid flow and heat transfer between two vertical porous plates moving in opposite directions: Sensitivity analysis

Abstract

The hydromagnetic convective flow between two parallel plates has been analyzed frequently. However, only a countable number of studies are accounted for the flow between parallel plates moving in opposite directions. The present work aims to analytically explore the three-dimensional (3D) convective hydromagnetic hybrid nanoliquid (with suspended Al2O3 and Fe3O4 nanoparticles) flow between two oppositely moving vertical porous plates utilizing the perturbation technique. The consequence of effectual parameters on the flow profiles is analyzed with the aid of graphs using MATLAB software. It is perceived that nanoparticle volume fraction ascends drag coefficient and descends temperature and main flow velocity. Furthermore, the rate of heat transfer is statistically scrutinized utilizing response surface methodology and sensitivity analysis. It is noted that the Nusselt number is most sensitive with the injection parameter. 3D surface plots are used to illustrate the parallel effect of pertinent parameters on the drag coefficient. Moreover, the present study finds applications in several engineering, geophysical, and industrial fields, such as in heat exchangers and faulting.
