Abstract

Drying chamber integrated with solar collector has been introduced as one of the new advanced technologies and environment friendly process for drying agriculture products. To propose a proper drying chamber integrated with solar collector for specific products, uniform distribution of velocity and temperature in the chamber need to be considered. Computational Fluid Dynamics (CFD) Ansys Fluent 16.0 software is used to study and analyse the air flow and temperature distribution pattern within the drying chamber in order to reduce experimental time and avoid high cost. A validation results of a journal studying indirect solar food dryer is carried out using CFD. The validation is done by comparing the data experiment from the study journal with the data obtained from the CFD simulation. The results show that the maximum mean temperature difference on the symmetry plane of solar drier between the CFD Simulation in study journal and CFD validation is found to be 2.3 K. The CFD simulation shows high agreement with the results in study journal which shows that the CFD simulation’s setting are correct and acceptable. With the purpose of improve the uniformity of airflow and temperature distribution in the drying chamber integrated with solar collector, three parameters are evaluated in this research which improve the weakness of the solar collector integrated drying chamber in the journal studied. The purpose of this study project is to investigate the performance of velocity and temperature distribution in drying chamber integrated with solar collector using three-dimensional (3D) CFD simulation in transient state condition. It was found that Parameter 3 (b) shows more uniform air flow velocity and temperature distribution with mean velocity 0.08m/s and mean temperature distribution 320.4K as compared to others design.
