摘要
在当前工作中，利用磁力提高了受灰尘积聚影响的光伏热（PVT）装置的生产率。磁力被应用于带有 Y 形翅片的冷却管道，而太阳辐照则作为热源被纳入方程中。通过调整光学特性来模拟灰尘的影响。热电发生器（TEG）层的加入提高了电力输出。冷却液为均匀的水和氧化铁混合物。灰尘的积累导致热性能下降了 9.3%，但磁力的使用提高了电效率。添加剂的浓度越高，系统性能越好，在最高进气速度（Vinlet）下的最大增益为 15.88%。提高 Vinlet 可进一步提高热效率（ηth）10.96%、光电效率（ηPV）1.16% 和热电效率（ηTE）33.53%。此外，洛伦兹力的应用还使等温均匀性提高了约 5.91 %。
Simulation of behavior of solar panel in existence of nanomaterial as cooling system
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.
