A horizontal heat generating square conduit with thin shell construction

一个横的薄壁结构的发热的方槽可以看作是没有间隙的双槽形结构。沿竖的中央对称轴线对剖开并在两半之间留个间隙,可以大大地增加薄壁的散热。在这种情况下,薄壁的内部表面亦成为有效的散热面积。这种结构在大电流母线和电子线路上有一定的实际应用。但是它的散热特性至今尚未见到有系统性的研究报导。为了提供设计依据,本文用实验方法研究了H=46毫米和H=92毫米二种规格的双槽形发热体在不同间隙开度条件下的散热,间隙开度范围自0至∞。实验参数范围;q:250~2450大卡/米~2小时,△t:22~128℃。最后结果以无量纲关系形式表出在图上。对于封闭的方槽,外表面的对流换热要比相应的横园柱的对流换热低得多,并可综合成下列公式:从s=0出发,随着s数值的增加,对流放热强度先是增加的,当s/H=0.33时趋近于最高值;对于大开度,再增加s,对流放热强度反而降馒;当s/H>1.5时,对流放热强度已经降到s=∞时的值。本文还包括纹影技术的研究。摄取了不开间隙开度条件下的纹影照片。从这些照片上可以看出,在内表面的上角部分向上流动的竖壁上的边界层被新生的横壁上的边界层冲散;在散热最有利间隙开度时,双槽体内部气流具有一种拔风作用。

Presented in this paper are the experimental results of impingement coolingof two aluminium targets of different sizes with six impingement tubes. The target simulating the leading edge of a turbine airfoil is preheated and cooled by jets of different impingement tubes at various flowrates and distances. The Lumped-Capacity method is used to determine the cooling rate 'of the aluminium target and the mean heat transfer coefficients which are in turn correlated indimensionless parameters. With the aid of a computer the relation between Nusselt Numbers and Reynolds Numbers including three dimensionless geometrical parametersis correlated in a generalizd expression Satisfactory results are obtained when the Nussult Numbers calculated from the recommended expression are compared with those by experiments. The recommended expression is further compared with the correlated formula of Arizona State University by Metzger and those of University of Cincinnati by Ravuri and Tabakoff together with the experimental data and it is found that the expression correlated by this paper is more or less reasonable.

本文用六种冲击管对两种尺寸的铝质试验件进行冲击冷却实验。模拟叶片前缘的试验件予先加热,然后由不同的冲击管喷出的射流在不同的流量和距离下对它进行冲击冷却。采用集总热容法来确定铝块的冷却率从而算出冲击平均换热系数,并整理成准则形式。通过计算机的运算得出Nu数与R6数以及三种无因次几何参数的统一的准则关系式。用该式计算出来的Nu数同本文实验测得的Nu数进行了比较,取得比较满意的结果。最后用该式与美国亚利桑那州大学的梅茨格公式和辛辛那提大学的拉维利——塔巴戈夫公式同本文实验数据进行了比较,认为本文整理出来的公式是比较合理的。

The four coefficients A, B,C and D of the correlation of ideal gas heat capacity, Cpo =A+BT + CT2 + DT3, were determined for 435 substances by the method of least squares with a digital computer, on the bases of the recently published Cpo data during the period of 1968 to 1978. The average percent deviation of the calculated Cpo from the experimental value is 0.160. The substances were selected according to their relative importance in fundamental chemical industries.

The four coefficients A, B,C and D of the correlation of ideal gas heat capacity, Cpo =A+BT + CT2 + DT3, were determined for 435 substances by the method of least squares with a digital computer, on the bases of the recently published Cpo data during the period of 1968 to 1978. The average percent deviation of the calculated Cpo from the experimental value is 0.160. The substances were selected according to their relative importance in fundamental chemical industries. Amongst these, either their heat capacity coefficients have not been published in the literature or their heat capacity coefficients are revised in the present work by using recently available published experimental data.

根据1968年至1978年期间新近发表的C_p~o数据,最小二乘法由电子计算机计算,确定了435种物质的理想气体热容C_p~o与温度的四项关联式C_p~o=A+BT+CT~2+DT~3中的常数A、B、C、D。计算的C_p~o值与实验值的平均百分误差为0.160。这些物质是按它们在基本化学工业中的相对重要性选择的。它们或是还没有C_p~o的温度关联式,或是虽然已有这种关联式,但并不是基于新近发表的C_p~o数据。
