Cold plasma is a novel nonthermal technology that has been used for preserving and maintaining the quality of food materials. Researchers developed numerous cold plasma equipment to study the effect of plasma on food materials; however, the degree of processing such as flow of plasma species from the source of plasma to the food material and their interaction/diffusion into the food, differs with respect to the equipment. The computational study can simulate the flow dynamics of plasma which in turn can improve the efficiency of processing and design aspects. Computational fluid dynamics (CFD) is the most reliable, cost-effective, and robust numerical tool used for simulating various high-end food processing technologies. In cold plasma processing, computational study aids in revealing the distribution of reactive species and their flow dynamics on the target surface. As CFD studies on plasma interaction with food materials are not available, this review is focused on covering the basics of using CFD in cold plasma simulation. It also explores the significant use of CFD in cold plasma simulation in various sectors along with its possible and futuristic applications in food processing.

计算冷等离子体动力学及其在食品加工中的潜在应用

冷等离子体是一种新型非热技术，已用于保存和保持食品材料的质量。研究人员开发了许多冷等离子体设备来研究等离子体对食品材料的影响；然而，处理程度，例如从等离子体源到食品材料的等离子体物质的流动以及它们在食品中的相互作用/扩散，就设备而言是不同的。计算研究可以模拟等离子体的流动动力学，从而提高处理和设计方面的效率。计算流体动力学 (CFD) 是用于模拟各种高端食品加工技术的最可靠、最具成本效益和稳健的数值工具。在冷等离子加工中，计算研究有助于揭示活性物质的分布及其在目标表面上的流动动力学。由于没有关于等离子体与食品材料相互作用的 CFD 研究，本综述重点介绍了在冷等离子体模拟中使用 CFD 的基础知识。它还探讨了 CFD 在各个领域的冷等离子体模拟中的重要用途，以及它在食品加工中的可能和未来应用。
