摘　　要：建立耦合插板的太阳能烟囱模型并对其进行数值计算,调查了不同插板间距及插板数量对烟囱通风性能的影响。研究表明,透明插板将在烟囱通道中形成热边界层来提升热压转换效率,从而提高了太阳能烟囱的通风能力。耦合单块插板时,插板间距为d/D=3/5时烟囱通风量最大,此时如果改变插板材料的吸收率,烟囱通风效果会更好。此外,当插板数量增加时烟囱通风量呈现增加的趋势。A solar chimney model with coupled panels was established and numerically calculated.The influences of different spacing and number of panels on the ventilation performance of the chimney were investigated.The study shows that the transparent panel will form a thermal boundary layer in the chimney passage to improve the thermal pressure conversion efficiency,thus improving the ventilation capacity of the solar chimney.When coupling a single insert,the chimney ventilation is maximum when the spacing of the inserts is d/D=3/5.At this time,the chimney ventilation will be better if the absorption rate of the insert material is changed.In addition,the chimney ventilation shows an increasing trend when the number of inserts increases.
