摘要
目前,越来越多的日光温室作业者通过在温室土壤中铺设热水循环地埋管道的方式来为温室夜间生产供热。为了了解温室地埋管道温度场的影响因素,运用GAMBIT建立土壤中不同直径的地埋管道二维网格模型,并采用Fluent软件模拟地埋管在冬季夜间环境下周围土壤温度场的变化。在网格模型中选取监测点,通过观测监测点温度了解埋管结构参数与土壤温度场的关系,为今后温室地埋管的埋设提供参考。
At present , more and more greenhouse operators make hot water circulating through the laying of buried pipes in the greenhouse soil in a way to produce heat for the greenhouse at night .In order to know the factors affecting green-house buried pipeline temperature field , using GAMBIT to establish a buried pipelines with different diameters in the soil of two-dimensional grid model , and using the Fluent software to simulate buried pipe in the changes of the soil tempera -ture field around the winter night environment .Selecting monitoring points in the grid models , observing the monitoring point temperature to understand the relationship between the structural parameters and the soil temperature field .It will provide the reference for the future of the buried pipes buried in greenhouse .
