摘要
本文对太阳能烟囱自然通风模型进行了数值模拟研究.分析了太阳能烟囱在多种情况下,气流的温度场和速度场分布,从而得出通风量与烟囱高度、进风口面积、出风口面积、加热面之间的关系.研究表明,通过合理的设计,可以利用太阳能烟囱增强自然通风效果.
The model of natural ventilation of solar energy chimney is studied by simulation.The distribution of temperature and velocity fields of the air flow at different situation are analyzed.Based on the analysis,the relationship of flow rate with some parameters,such as the height,inlet section,outlet section and heated area of the chimney is established.The study shows that the natural ventilation can be improved by rational design of solar energy chimney.
