| 摘 要： | 运用三维不可压缩流体的紊流模型,对蔬菜大棚内气流场进行了数值模拟,分析研究了不同形状、不同换气条件的蔬菜大棚内部气流流态,为进一步优化蔬菜大棚结构提供了可靠的依据。对抛物型、屋脊型等多种大棚形式作了内部气流流态模拟,每种形式又分不开侧窗和开侧窗二个工况。从各种形式和工况的模拟结果可清楚地看出,大棚内部气流的速度分布及回流位置、范围都比较合理。

| Abstract: | Velocity field inside the greenhouse is studied by numerical simulation theory of three-dimensional uncompressible turbulent model. It provides more reliable proof to optimize structure of greenhouse by analyzing airflow inside the greenhouse of different shapes and different conditions of exchanging gases. Airflow inside greenhouse such as Parabola greenhouse and fastigium greenhouse have been simulated with the working status of opening the side windows and not opening the side windows.The results indicate from all kinds of greenhouse and the ending of simulation that the distribution of gas and position and scope of turble are comparatively reasonable. |
