| 摘 要： | 基于CFD模拟技术,采用标准K-ε湍流模型和Do辐射模型对自然通风温室在3种通风型下的室内气流分布进行了2-D求解,并对3种模拟结果进行了比较和分析。结果表明:在温室两侧开有侧窗、顶部开有天窗的通风情况下,温室内部的通风状况最好,而且风速适中,适宜作物生长。

| Abstract: | The 2-D simulation of airflow field under three kinds of ventilated type was done based on the CFD technique for the natural ventilation greenhouse.The standard K-ε model and Do model were used for the process of simulation.The three kinds of simulation results were compared and analyzed.The results showed that the configuration of both sides and roof ventilation was the best pattern for ventilation.The wind speed was moderate and suitable for the growth of crops. |
