โฆ Synopsis
m A flow regime map for the vertical downward air-water system is proposed. Three distinguished flow regimes are observed: annular, slug, and bubblyโข The map is compared quantitatively with two other maps from the available literature. The transition boundaries between the three flow regimes are estimated on the basis of void fraction values.

In a certain range of gas velocities it is possible to hold a quantity of liquid as a fihn on the walls of a vertical tube, there being no net movement of the liquid. Pressure drop and hold-up measure- ments have been made in this regime using air and water. A theoretical relationship between the tw
