摘　　要：随着计算流体力学数值模拟技术的不断成熟,精确性和可靠性的不断提高,近年来在农产品冷链物流中得到广泛的应用,对提高冷藏类食品所需低温环境的温度均匀性、确定货物堆栈方式、合理控制制冷时间、以及对提高整体冷链物流经济效益都具有重要意义。本文具体阐述了计算流体力学数值模拟技术的前处理、求解和后处理3个阶段,并回顾该技术应用在农产品冷链物流存储、运输和销售过程中的研究进展,分析归纳了存在的优势和不足,展望了计算流体力学应用在农产品冷链物流领域的未来发展趋势。With the development of computational fluid dynamics, the simulation accuracy and reliability are improved constantly. This technology is widely used in agricultural cold-chain logistics for the past few years which has significances to raise temperature homogeneity of the low-temperature environment, determine the goods stack, reasonably control refrigerating time, and improve the economic benefits of overall cold-chain logistics. This paper mainly described the pre-processing, computation and post- processing of computational fluid dynamics, reviewed the research advance of it in store, transportation and market process of agricultural cold-chain logistics, expounded the research methods and application characteristics of the technology, generalized and analyzed the advantages and deficiencies. Moreover, the paper also looked into the future trends of computational fluid dynamics in agricultural cold-chain logistics applications.
