Abstract In this research we investigate whether charged sprays offer any improvements over conventional spray in the spray-chilling of meat. A Eulerian-Lagrangian CFD modelling approach is developed and validated with results from automotive spray painting. The model is then extended to include evaporation and the transport of evaporation products. The simulation results show doubling of the spray transfer efficiency as well as a notable increase in the rate of cooling when electric charge is applied to the spray. Furthermore, the presented modelling approach yields consistent results at low computational costs, making it suitable for use in future design optimisation studies.

喷雾冷却中蒸发带电喷雾的数值模拟

摘要 在这项研究中，我们调查了带电喷雾在肉的喷雾冷却方面是否比传统喷雾有任何改进。开发了欧拉-拉格朗日 CFD 建模方法，并使用汽车喷漆的结果进行了验证。然后将模型扩展到包括蒸发和蒸发产物的传输。模拟结果表明，当对喷雾施加电荷时，喷雾传递效率加倍，冷却速度显着增加。此外，所提出的建模方法以低计算成本产生一致的结果，使其适用于未来的设计优化研究。
