Nowadays, numerical modelling has been extensively converted to a powerful instrument in most agricultural engineering applications. In this study, a mathematical model was developed to simulate the forced-air cooling process of mushroom. The simulation was performed in CFD code Fluent 19.2 and the conservative mass, momentum and energy equations were solved within the package. The accuracy of the model was then quantitatively validated against experimental data and very good agreement was achieved ( ). It was confirmed that in addition to convective mode, water evaporation makes a major contribution in mushroom cooling. According to the results, the developed model was able to predict the velocity and temperature profiles with a reasonable accuracy. It also has a potential to be used in design and optimization of such processes.
如今,数值模拟已广泛转变为大多数农业工程应用中的一种强大工具。在本研究中,开发了一个数学模型来模拟蘑菇的强制风冷过程。模拟在CFD软件Fluent 19.2中进行,在该软件包内求解守恒的质量、动量和能量方程。然后根据实验数据对模型的准确性进行了定量验证,结果取得了很好的一致性( )。结果证实,除了对流方式外,水分蒸发对蘑菇冷却也有很大贡献。根据结果,所开发的模型能够以合理的精度预测速度和温度分布。它还具有用于此类过程设计和优化的潜力。
