Abstract
The study of efficient heat transfer fluids over a sheet under the influence of catalytically active and magnetised phenomena is crucial across various industrial settings due to its potential to address thermal dynamic challenges. This study investigates the thermal transport efficiency of trihybrid nanofluids by employing the Carreau model with temperature-dependent viscosity over a radiated heated surface. This physical model incorporates homogeneous-heterogeneous chemical reactions for catalyst-driven processes on the thermal transport of nanofluids. The study aims to examine the influence of temperature-dependent viscosity and the influence of magnetic and radiative effects on heat transfer in trihybrid Carreau nanofluids over a sheet. The physical model contains the coupled set of partial differential equations (PDEs) that are converted into ordinary differential equations (ODEs) using similar transformations. The numerical solution is obtained using the bvp4c algorithm. The velocity of nanofluids is intensified with augmented values of the model index because THNF experienced a sharper reduction in viscosity due to higher shear rates. Overall, key findings revealed that the viscosity-temperature dependency and magnetic and catalytic influences significantly enhance heat transfer efficiency, showcasing the potential for performance optimisation in heat-sensitive applications.
