what is plug flow in capillaries
The present work is an attempt to address this problem, by analyzing the flow of an isolated liquid plug which is in direct contact with the capillary tube wall. FIG 1: Two configurations of gasâliquid flow in a capillary tube: (a) wet-plug flow re-gime and (b) dry-plug flow regime.olume 3, Issue 2-4, 2012Thermal Transport Behavior of a Liquid Plug Moving inside a Dry Capillary Tube 113 The radial location by Thulasidas et al. (1997) is given only for developed ve-locity profile in wet-plug flow which in this case is for L/D = 2 and 4.
