日光温室稳态温度场的数值模拟

摘要

根据质量、动量和能量守恒定律,利用对太原地区某自然通风日光温室温度场连续测试得到的相应数据,建立了该类自然通风日光温室的数学模型,应用新建数值模型,对自然通风日光温室内温度场的分布情况进行了稳态的模拟,结果表明：在稳态条件下,模拟值与现场测试数据有较高的吻合度,此模型可用于该类自然通风日光温室温度场的预测。%According to quality,momentum,and energy conservation law,making use of the corresponding test data gained from continuous test of the temperature filed in a natural ventilation sunlight greenhouse in Taiyuan,the paper establishes the mathematical model of the natural ventilation sunlight greenhouse.Applying new numerical model,it carries on stable simulation of the distribution law of temperature field in natural ventilation sunlight greenhouse.Results show that： under the stable condition,the simulation value is identical to in-situ testing data.Thus,the model can be used in the prediction of temperature filed in natural ventilation sunlight greenhouse.
