| description | The thermal transport in hybrid nanofluid flow across a rotating disk has numerous applications in technical and engineering fields, including thermal power systems, rotating machinery, gas turbines, and electronics. The Hybrid nanofluids offer better thermal efficiency than traditional single-component nanofluids due to the inclusion of two types of metallic nanoparticles. This study examines the thermal behavior of an Ag−GO/KO hybrid nanofluid flowing over a rotating, slippery disk under a highly oscillating magnetic field. The model incorporates a thermal sink/source and thermal radiation to enhance its applicability in practical scenarios. The Tiwari and Das approach is used to examine the characteristics of the fluid flow. The model equations are obtained by applying the proper Von-Karman similarity transformations to the strongly non-linear system of governing equations, which is then numerically solved using the bvp4c technique in MATLAB. The effects of physical parameters on thermal field, radial velocity, axial velocity, and tangential direction are visually displayed. The findings indicate that a rise in the inertia coefficient and porosity variable leads to produce a reducing effect on the radial velocity and tangential velocity. In contrast, the opposite impact is examined in the axial direction. Additionally, the result demonstrates the improved temperature distribution due to higher thermal radiation and unsteady variable. Moreover, tables are depicted to numerically discuss the impacts of slip variables, heat radiation and unsteady variables on drag coefficients and heat transport. |
