Abstract

The present investigation focuses on examining the thermophysical characteristics of flow in a gap between rotating cone and circular discs utilizing hybrid nanofluids, owing to its varied applications. The enhanced thermal conductivity of nanofluids proves particularly valuable in cooling systems, diminishing energy consumption, preventing overheating, and enhancing the overall performance of electronic devices, among other benefits. The convectional flow of conductive fluid under the influence of magnetic field and thermal radiation significantly influences the flow dynamics. Moreover, the consideration of dissipative heat, including the combined effects of viscous and Joule dissipation, amplifies the flow properties. The complex nonlinear system of equations, initially presented in dimensional form, undergo transformation into a nonlinear ordinary system in non-dimensional form through the introduction of appropriate similarity rules. Various profiles are then generated using bvp4c built-in function supported in MATLAB and depicted graphically. To optimize the responsiveness of Nusselt number with respect to various factors, a robust statistical approach known as response surface methodology is employed. Statistical validation is carried out using analysis of variance through hypothetical testing.
