Abstract
The paper is concerned with the gas void fraction on a perforated plate under gas-liquid crosscurrent flow.
Experiments were carried out under a variety of plate geometries, weir heights, weir widths, liquid flow path lengths, gas and liquid rates and physical properties of liquids.
The mean gas void fraction on a plate is found to be correlated in terms of the Froude number based on clear liquid height and free area. For so-called foaming materials, the mean gas void fraction shows a maximum value at a specific Froude number, and then approaches the values of non-foaming ones.
