摘要

该研究考虑了当代填料薄膜装置中的流体力学问题，这些装置具有管状和平面通道，以及下流共流状态下的层流和湍流气流和液流模式。假设各相之间的流体力学相互作用较弱，气相中没有速度循环。采用近似 Schlichting 方法求解。确定了各相的速度分布、下流膜的厚度以及液态和气态入口流体动力区域的大小。

Liquid and Gas Hydrodynamics in Film Regular Sprayed Packings in a Cocurrent Downflow Regime

The work considers the hydrodynamics in contemporary packed film devices with tubular and plane channels and laminar and turbulent gas- and liquid-flow patterns in a downflow cocurrent regime. Weak hydrodynamic interaction between the phases and no velocity circulation in the gas phase are assumed. The solution is found by the approximate Schlichting method. The distribution of velocities in the phases, the thickness of the downflowing film, and the sizes of the inlet hydrodynamic areas in the liquid and gas are determined.
