摘要
在矩形平面热源上方的浮力射流流量的理论公式基础上进行了数值求解,提出了适用于确定近正方及宽带状矩形平面热源上方诱导气流量的近似公式,并且将热分层高度与阿基米德数Ar结合了起来,为评价置换通风房间的通风效果提供了方便.
Based on the theoretical formula of flow rate of buoyancy jet above plate heat sources, mathematical calculation is carried out. The approximate formulae for calculating the induced flow rate above near square or belt like plate heat sources are proposed. Furthermore, the combination of the thermal stratification height and the Ar number is convenient for estimating the ventilation effectiveness of displacement ventilation.
