A comprehensive analytical study conducted by researchers highlights the significant potential of magnetized Casson hybrid nanofluids, comprising copper (Cu) and graphene oxide (GO) nanoparticles suspended in kerosene oil, to improve heat transfer efficiency for industrial cooling applications. This innovative approach is pivotal as industries seek advanced cooling solutions.
The study investigates the time-dependent flow of these hybrid nanofluids over radially stretching sheets, addressing how magnetic fields and thermal radiation can optimize heat transfer processes. The impetus for this research stems from the increasing demand for efficient thermal management systems capable of enhancing cooling mechanisms across various industrial sectors.
Researchers employed the Homotopy Analysis Method to arrive at solutions for the nonlinear equations governing the flow and thermal distribution, integrating the Darcy-Forchheimer model, which is instrumental for analyzing fluid behavior in porous materials. These methods are expected to yield insights advantageous for enhancing thermal conduction systems.
One standout finding from the analysis is the notable efficiency with which the Casson hybrid nanofluid can transfer heat. At a nanoparticle volume concentration of 0.03, this innovative fluid demonstrated extraordinary results—achieving nearly a 19.99% increase in heat transfer efficiency compared to conventional nanofluids and standard fluids. This significant enhancement confirms the superior thermal properties of hybrid nanofluids.
The presence of the magnetic parameter was found to dampen the fluid’s velocity profiles due to Lorentz forces but simultaneously improved thermal mixing. This effect is particularly pronounced within the Casson hybrid nanofluid, showcasing its capacity to maintain temperature uniformity effectively, which is critically important for many industrial operations.
Crucially, the research also examines various factors influencing the performance of these nanofluids under real operational conditions. The study found suction effects improve the velocity profiles by bolstering momentum and ensuring more effective mixing within the fluid, particularly highlighting the advantage of the Cu and kerosene oil mixture over other forms. Conversely, injection tends to negatively affect the velocity and temperature profiles.
With substantial research backing the applications of hybrid nanofluids, this study positions Casson hybrid nanofluids as promising candidates for various cooling applications—including automotive radiators, microelectronics, and solar energy systems—where efficient heat transfer is imperative.
Future studies will explore the performance of different hybrid nanofluid compositions and concentrations, which could pave the way for even more refined applications and methods for industrial cooling and thermal energy management.
