摘要

本研究中对D_g50mm的十一种乱堆填料以空气-水系统在不同喷淋密度下测定了不同气速的压降值及泛点值。在已取得的大量数据的基础上

分析了Eckert通用关联图法

认为这种方法存在一些缺点。本文提出了改进的计算方法:采用下式以计算泛点气速采用下式以计算压降 △P=mY/（1-nY）式中本文成功地关联了取得的数据

对十一种填料整理出特征值——形体常数α及压降常数m、n。

Abstract

In this research

the pressure drop data at different gas velocities and flooding point data have measured with the air-water system at different irrigating rates for eleven random tower packing of Dg50mm. We found some disadvantages in J. S. Eckerts method and think that it is not suitable to be used as the foundation for further modification

On the basis of the researches done by our predecessors

we have in this article

suggested two new equations

one for calculating the flooding velocity the other for calculating the pressure drop
