Addressing the demand for steady energy supply and overheating prevention, this research models melting heat transfer in a ternary hybrid nanofluid under solar radiation and magnetic fields in squeezing flow. The fluid comprises copper, silicon dioxide, and zirconium dioxide nanoparticles mixed into an engine oil base. Mathematical modelling incorporating entropy generation minimisation was evaluated using spectral collocation and finite element methods. Results show that introducing the three-component nanoparticles improves thermal characteristics, while higher solar radiation intensifies the fluid energy profile. In contrast, stronger magnetic forces reduce the fluid velocity distribution. These insights describe heat transfer dynamics across specialised fluid environments.
Managing heat efficiently is essential for preventing equipment overheating and improving energy productivity in industrial and domestic settings. Understanding how multi-component nanofluids transfer heat under magnetic and radiative conditions helps engineers design more effective heating and cooling processes, supporting advancements in thermal energy management and temperature control technologies.
The abstract highlights potential applications in ice and snow melting, solar thermal energy storage, and the food industry. Target users include thermal system designers and equipment manufacturers. However, as the work is based on numerical simulations and mathematical modelling rather than physical testing, it represents early-stage research that requires experimental validation before real-world commercial use.

The increasing need for a steady energy supply to enhance efficiency is progressively growing in both residential and manufacturing industries. This demand can be addressed by utilizing advanced technologies like a melting heat generator to produce significant amounts of heat and prevent overheating. Based on the above applications of melting heat, the consequences of melting heat transfer induction on ternary hybrid nanofluid (T-HNF) exposed to solar radiation mechanism in an erratic squeezing flow are considered. The nanoparticles Copper (Cu), Silicon dioxide (SiO2), Zirconium dioxide (ZrO2) are immersed in base fluid Engine oil (EO) resulting in T-HNF (Cu + SiO2 + ZrO2/EO). The model equation also takes into account the entropy generation minimization and Bejan number. Both the spectral collocation technique (SCT) and finite element scheme (FES) are applied to solve the ordinary differential equations (ODEs) through the Mathematica package. Our results reveal that the impact of three-component nanoparticles increases, while the solar radiation parameter raises the energy profile. Also, an increase in the magnetic field deteriorates the velocity distribution. The research has various potential applications, such as in ice and snow melting, solar thermal energy storage, and the food industry.
