Entrance effects in a developing slug flow
The kinetics of a Taylor bubble, as it rises behind a series of other bubbles in a gas-liquid slug flow, have been determined. The rise velocity of a bubble is expressed as a function of separation distance from the bubble ahead of it. Using this information, the pattern of development of bubbles wh...

| description | The kinetics of a Taylor bubble, as it rises behind a series of other bubbles in a gas-liquid slug flow, have been determined. The rise velocity of a bubble is expressed as a function of separation distance from the bubble ahead of it. Using this information, the pattern of development of bubbles which initially enter a tube at regular intervals is determined by means of finite difference calculations. The density and, to a first approximation the pressure drop, of the developing flow are then calculated from continuity considerations The density distritution in the entrance region is found to be a function of flow rates of the two phases, of distance from the inlet, and of initial bubble size0 Density calculated by the present theory is compared with experimental measurements by the present and other investigators. Theory and experiments are generally in good agreement. |
