Numerical Study of Soret and Dufour Mechanisms in Mixed Convective Heat and Mass Transport of Hybrid Nanoparticle Suspensions in a Non- Newtonian Fluid

The Soret and Dufour effects in heat and mass transport in magnetohydrodynamic three-dimensional cross-fluid flow are examined in this article. The hybrid nanoparticles\(\:\:{Al}_{2}{O}_{3}\), \(\:Ti{O}_{2}\) and \(\:Cu\) are considered to be dispersed in ethylene glycol to examine which of mono, di-, and tri-nanoparticles are the most effective in enhancing the thermal permal of the ethylene glycol. The stretching of the surface induces flow to be created. In the presence of thermal radiation and the Soret and Dufour effects, the equations for energy and concentration are modified. A cross fluid is thought to transmit electricity as it passes across a consistent magnetic field. The strong nonlinear ordinary differential systems are obtained by appropriate transformations. The application of bvp4c solves the mathematical models. Graphs are used to interpret and provide detailed illustrations of the effects of many parameters. For a range of values of the related parameters, calculations for the local Nusselt and the local Sherwood numbers and skin friction coefficients are shown and discussed. The Hall and ion slip currents are observed to increase the thickness of the momentum boundary layer. Numerical simulations have demonstrated that a drop in fluid velocity is implied by an increase in the Weissenberg parameter. Additionally, it is shown that the cross-rheological fluid's boundary layer region is shorter than that of Newtonian fluids. Electrical energy is transformed into internal heat via ohmic dissipation, which unnecessarily raises the fluid's temperature and lowers its effective heat transfer capacity. This extra thermal energy can reduce temperature gradients, thicken the thermal boundary layer, and reduce the efficiency of heat transmission in general. Therefore, it is advised to employ fluids with little to no Ohmic dissipation in order to ensure optimal heat transmission and enhanced thermal system performance. For a favorable Buoyancy force, fluid velocity increases, and temperature decreases. Temperature increases when the values of the Soret number (\(\:Sr\)) and Dufour number (\(\:Df\)) are increased.
