Abstract
In current work, the productivity of a photovoltaic thermal (PVT) unit impacted by dust accumulation was improved using magnetic force. The magnetic force was implemented to a cooling duct with Y-shaped fins, while solar irradiation was included as heat sources in the equations. Dust effects were simulated by adjusting the optical properties. The addition of a thermoelectric generator (TEG) layer boosted the electrical output. The cooling fluid was a homogeneous water and iron oxide mixture. Dust accumulation led to a 9.3 % drop in thermal performance, but the use of magnetic force enhanced electrical efficiency. Higher concentrations of additives improved system performance, with a maximum gain of 15.88 % at the highest inlet velocity (Vinlet). Increasing Vinlet further improved thermal efficiency (ηth) by 10.96 %, photovoltaic efficiency (ηPV) by 1.16 %, and thermoelectric efficiency (ηTE) by 33.53 %. Moreover, the application of Lorentz force increased isothermal uniformity by approximately 5.91 %
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.
