Abstract

Enhancing the thermodynamic performance of systems including thermal exchanging devices, solar collectors, and thermally controlled instruments is crucial for industrial advancements. This investigation probes the thermal performance of water in a crown-shaped chamber infused with Cu-CuO-Al₂O₃ ternary hybrid nanoparticles. Unlike previous studies focusing on simpler geometries and binary nanofluids, this work introduces a novel chamber design with a heating element of varying aspect ratios with magnetic field effectiveness. The governing equations are modeled using partial differential equations, incorporating the thermophysical characteristics of the ternary nanofluid. Finite element simulations are performed in COMSOL Multiphysics, with mesh independence verified. Results show a remarkable 360 % upsurge in the average thermal flux, highlighting the superior heat transfer capabilities of ternary nanofluids and the influence of advanced geometrical designs. These findings emphasize the potential of ternary nanofluids in optimizing thermal systems.

期刊介绍： Case Studies in Thermal Engineering provides a forum for the rapid publication of short, structured Case Studies in Thermal Engineering and related Short Communications. It provides an essential compendium of case studies for researchers and practitioners in the field of thermal engineering and others who are interested in aspects of thermal engineering cases that could affect other engineering processes. The journal not only publishes new and novel case studies, but also provides a forum for the publication of high quality descriptions of classic thermal engineering problems. The scope of the journal includes case studies of thermal engineering problems in components, devices and systems using existing experimental and numerical techniques in the areas of mechanical, aerospace, chemical, medical, thermal management for electronics, heat exchangers, regeneration, solar thermal energy, thermal storage, building energy conservation, and power generation. Case studies of thermal problems in other areas will also be considered.
