摘要
介绍了果园风场与雾场CFD建模方法与田间试验方法。CFD模拟用来评估自然风、喷雾机类型在不同果园种植模式下对风雾场的影响,并通过田间试验进行验证。为此,从风场的测量与建模方法、雾场的测量与建模方法、风雾场与果树之间的交互作用3个方面对现有研究进行综述,阐述了外部影响因子对风场分布的重要作用,分析了雾场分布与风场分布的直接关联,明确了风速和风量在果园风送喷雾风力调控系统中的基础作用,旨在实现按需施药及提高农药利用率。最后,指出了果园风场与雾场建模方法未来发展方向:①探索既完整准确又经济快速CFD建模方法仍是研究热点;②获取自然环境和喷雾机类型等影响因子与风场分布参数之间的定量关系,是未来重要的研究方向;③随着研究的深入,CFD建模方法有望在果园精准喷雾技术中发挥现实意义。
    This paper reviews computational fluid dynamics(CFD) models of airflow and spray application and laboratory tests in orchard. CFD simulations were validated using field trails and used to assess the effect of wind and sprayer type on spray distribution in different orchard planting patterns. The research progress analysis focuses on three methodologies: orchard airflow field modeling and measuring method, orchard droplet field modeling and measuring method, interaction between orchard tree and airflow and droplet field. Important differences in airflow pattern with different external influence factors were summarized. The direct links between liquid distribution and generated airflow pattern were discussed. To adjust airflow of the air-assisted sprayer, air speed and air volume, which is the basic information for airflow control in orchard air-assisted spraying, should be focused on. The ultimate goal of a pesticide spraying system is to provide adequate coverage on canopies with a minimum amount of pesticide and off-target waste. Finally, the future directions of modeling methods for orchard airflow and droplet field are pointed out: ①Developing an integrated and economical CFD modeling remains a research hotspot.②The study on the quantitative relationship between these influence factors and parameters of airflow distribution is an urgent need.③With the development of research, the CFD modeling methods are expected to play a realistic role in orchard air-assisted spraying technology.
