摘　　要：医药仓库对环境条件要求较高,柔性空气分布系统因纤维材质的渗透性和孔口送风的均匀性使其应用广泛。为了研究柔性空气分布系统应用于医药仓库的气流组织特性,为工程设计和实际应用提供指导,用ICEM CFD软件建立柔性空气分布系统物理模型,用FLUENT软件对3种孔口角度和两种货架摆放方式下仓库内温度和速度的分布情况进行模拟及实验验证。结果显示,实验值与模拟值吻合度在92%以上;在柔性风管系统风量一定时,货架横向摆放方式要优于竖向摆放方式,柔性风管送风孔口角度30°优于0°和60°,仓库内温度场更均匀,气流速度波动更小。建议工程中采用30°角送风孔口。Pharmaceutical warehouses have high requirements for environmental conditions.Flexible air distribution systems are widely used because of the permeability of fiber materials and the way of orifice air supply in order to study the air distribution characteristics of the flexible air distribution system applied in the pharmaceutical warehouse,and provide guidance for engineering design and practical application.ICEM CFD software is used to establish the physical model of flexible air distribution system,and FLUENT software is used to simulate and verify the distribution of temperature and velocity in the warehouse under three orifice angles and two shelf placement modes.The results show that the agreement between the experimental value and the simulated value is more than 92%;When the air volume of the flexible air duct system is fixed,the horizontal placement of the rack is better than the vertical placement.The angle of the air supply orifice of the flexible air duct is 30 better than O°and 60°.When the horizontal placement of the rack and the angle of the air supply orifice are 30°,the temperature in the warehouse is more uniform and the speed fluctuation is smaller.The suitable orifice angle of the air duct to the engineering is 30°.
