Abstract
Efficient thermal management is required in advanced engineering applications such as energy systems, electronics cooling, and industrial processes. The exceptional thermal properties of graphene quantum dots GQDs combined with the thermoelectric performance of bismuth selenide Bi2Se3 and the high conductivity of silver Ag provide significant advancements in heat transfer efficiency and thermal control systems. We explore, in this study, the novel thermal attributes of a ternary nano-composition consisting of GQDs + Bi2Se3+Ag particles suspended in Therminol VP-1. The incorporation of thermal radiation and activation energy offers insights into the temperature-sensitive processes. The analysis covers the features of three types of nano-compositions such as GQDs/Therminol VP-1, GQDs-Bi2Se3/Therminol VP-1 and, GQDs-Bi2Se3-Ag/Therminol VP-1. An order reduction approach is applied to streamline the mathematical modelling and computational efforts while preserving the system's accuracy. The analysis incorporates a machine learning technique based on recurrent neural network (RNN) to evaluate the nonlinear impacts of the physical parameters. The outcomes evidently disclose the fact that the volume concentration of bismuth selenide and of silver tend to elevate the temperature in usual, hybridized and tri-hybridized cases of nano-compositions. The heat transfer rate increased up to 24.5 % when the volume concentration of bismuth selenide and of silver increased up to 0.7 and 0.3 respectively. The activation energy substantially promoted the concentration in either case of nano-composition e.g., ternary, binary and pure nano-composition case.
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.
