Abstract

This study is concerned with the development of a finite element (FE) model using COMSOL Multiphysics for hybrid greenhouse dryers in humid subtropical climate of Ranchi, under no-load condition. The temperature and humidity distribution in the dryer was visualized using the FE model and compared against experimental data to evaluate its reliability in simulating dryer behavior. The performance evaluation conducted under no load condition showed that the efficiency of the proposed dryer was 42.35% and maximum overall convective heat transfer coefficient was 6.27 W/m²°C. The temperature inside the dryer ranged from 55°C to 80°C, while the relative humidity ranged from 37% to 45%. The developed FE model using COMSOL Multiphysics software, shows a close agreement between experimental and predicted results with a lower statistical error. Overall, this study's findings suggest that the hybrid greenhouse dryer could be a useful tool for drying crops in humid subtropical climates and the FEM could be a valuable tool for future research.

本研究采用 COMSOL Multiphysics 软件为兰契亚热带湿润气候下的混合温室干燥机开发了一个空载条件下的有限元（FE）模型。利用有限元模型对烘干机中的温度和湿度分布进行了可视化，并与实验数据进行了比较，以评估其在模拟烘干机行为方面的可靠性。在空载条件下进行的性能评估显示，拟议干燥机的效率为 42.35%，最大整体对流传热系数为 6.27 W/m2°C。干燥机内的温度范围为 55°C 至 80°C，相对湿度范围为 37% 至 45%。使用 COMSOL Multiphysics 软件开发的有限元模型显示，实验结果与预测结果非常接近，统计误差较小。总之，这项研究的结果表明，混合温室干燥机可以成为亚热带潮湿气候条件下干燥农作物的有用工具，有限元模型可以成为未来研究的宝贵工具。

期刊介绍： Energy Science & Engineering is a peer reviewed, open access journal dedicated to fundamental and applied research on energy and supply and use. Published as a co-operative venture of Wiley and SCI (Society of Chemical Industry), the journal offers authors a fast route to publication and the ability to share their research with the widest possible audience of scientists, professionals and other interested people across the globe. Securing an affordable and low carbon energy supply is a critical challenge of the 21st century and the solutions will require collaboration between scientists and engineers worldwide. This new journal aims to facilitate collaboration and spark innovation in energy research and development. Due to the importance of this topic to society and economic development the journal will give priority to quality research papers that are accessible to a broad readership and discuss sustainable, state-of-the art approaches to shaping the future of energy. This multidisciplinary journal will appeal to all researchers and professionals working in any area of energy in academia, industry or government, including scientists, engineers, consultants, policy-makers, government officials, economists and corporate organisations.
