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. [ABSTRACT FROM AUTHOR]
