Özet
The three-dimensional magnetohydrodynamic (MHD) tangential hyperbolic hybrid nanofluid flow (MoS2: Cu /H2O) is numerically analyzed across a porous stretching sheet in the presence of the Darcy Forchheimer porous media, varying thermal conductivity, and the effect of activation energy. In this case, the dispersant is MoS2 and Cu nanoparticles in a base fluid made water (H2O). The HNF has high thermal conductivity and heat transfer characteristics than the traditional nanofluids. These improved thermal properties have made hybrid nanofluids to be immensely utilized in medical technologies, heat exchangers, cooling devices, agricultural applications, electronic engineering, and the chemical industry. The model of the physical flow phenomenon is established in the form partial differential equations (PDEs). Appropriate similarity changes are utilized to converted the governing PDEs to ordinary differential equations (ODEs). The solving of the numeric equations of the temperature, concentration, velocity, and motile microorganism distributions is performed using the MATLAB inbuilt solver, bvp4c. The numerical findings are in excellent accordance with already published works proving the current model. Physical factors on the profile of motile microorganisms, temperature, velocity, and concentration are plotted using graphs and tables. It is noted that as Weissenberg number, rotation parameter, magnetic parameter, and Darcy-Forchheimer parameter are improved, the thickness of the velocity boundary layer declines whereas the thickness of the thermal boundary layer increases. The numerical results generally tend to fit the previously reported results.
