Thermophysical dynamics of mineral oil-based hybrid nanofluids under multiple flow conditions and radiation effects; Individual, synergistic, and shape impacts analysis

Considering the accelerated growth in usability of hybrid nanofluids in a range of sub-fields of various industries, this work’s fundamental aim is the essential evaluation of thermal dynamics and patterns forming during the flow process of a hybrid nanofluid. The particles, which take part in constituting a hybrid nanofluid, are aluminum alloys (Alu) and molybdenum-disulfide (MoS2 ), whereas the fluid serving as a host is mineral oil (MO). The consequential morphological influences of included particles are taken into consideration too by studying column, blade, tetrahedron, sphere-like, and lamina shaped structures. Besides explaining the conjoint advantages expected from the concurrent inclusion of MoS2 and Alu into MO, the separate inclusion of these particles is also examined. The under-evaluation problem’s geometry contains a vertical wall. The relevance of a few other determinants, including the flow across a porous medium, ability of the Lorentz force to drag back the flow speed, and fluctuations of the energy function with respect to radiation, is outlined. The steps taken to account for all the foregoing components mathematically result in a convoluted, non-linear, and implicit system of the fundamental mathematical functions. Prior to exercising the principal solutionsacquisition method, which in this study is the Laplace transform, the regular time-derivative is supplanted by a generalizing operator (Caputo–Fabrizio derivative) following the non-dimensionalization process. The successful completion of all these computational steps brings about exact solutions. More importantly, this work presents a solution for the velocity field in the form of a general time-based function, which is modifiable. To highlight the significance of this unique feature, the solution is adjusted for three different physical scenarios. A number of tables are formed, and figures are drawn to convey the information of considerable impact regarding critical physical quantities. From simulation process, an overall boost of almost 67% in the heat-conducting capability of mineral oil is recorded, which arises from the inclusion of MoS2 and Alu with homogeneous fractions. When it comes to thermal usefulness, the bar graph signifies that the hybrid nanofluid will perform way more efficiently when the particles are of a lamina-like shape. Similarly, a consequential drop of 11.20% in shear stress also takes place as an outcome of the hybridization.
