【摘要】 用稳态法进行了等温竖直平行平板间抽吸式自然对流换热的实验研究。着重研究了温差及间距对换热的影响,发现小间距及大间距有不同的换热规律。实验数据具有较高的精度,建立的经验公式在d/L=0.025-0.26、Ra_d=500-1.5×10~6的范围内,换热系数的相对误差不大于±12％。更多还原

【Abstract】 The results of the experiment on natural convective heat transfer from two isothermic vertical parallel plates under different temperature differences between plate and ambient and different spacings between plate and ambient are reported. The experimental correlations are valid under following range of parameters: d/L = 0.025-0.26,Rad=500-1.5×106.更多还原
