摘要
本文基于质量守恒和动量守恒定律,导出了Z 型布置并联管组的流动支配方程,得到了压降和速度的计算式。并提出了用结构特性系数φ~2表征流体在并联管组中流动的特点。最后对计算结果进行了分析和讨论。
Based upon the laws of conservation of energy and mass,a governing equa-tion for flows in parallel tubes with Z arrangement is derived and formulas forcalculation of the pressure drops and velocities in the tubes are obtained.Acharacteristic structure factor featuring fluid flow in parallel tubes is proposed.Finally,the calculated results are analysed and discussed in this paper.
