摘要
应用流体力学(CFD)软件Fluent,采用k-ξ紊流模型和非稳态求解方法,对加入货物冷藏车的温度场和湿度场进行了三维非稳态数值模拟计算,得到了冷藏车蒸发器区、中心区、货物区以及边壁等处的温湿度分布。冷藏车内流场的数值模拟结果可以为监测与控制冷藏车内的环境提供技术依据。
Three dimensional non-stable numerical simulations were conducted to simulate the temperature and humidity fields inside a refrigerated vehicle with cargoes. Fluent, a software for Computational Fluid Dynamics （CFD） was used, and the k-ζ turbulent fluid model was adopted with unstably solving method. The distribution characters of temperature and humidity were got around evaporator area, center area, cargo area and wall, etc. The numerical simulation results of fluid field in a refrigerated vehicle can provide technical supports for monitoring and controlling the environment inside a refrigerated vehicle.
