Webresearch is focused on microgravity slug flow. For slug flow, most of the work has been carried out in terrestrial gravity; very little work has been done with regards to two-phase flow modelling in microgravity conditions. No microgravity data was used in the development of the accepted models from Nicklin, Wilkes, and Davidson (1962) and WebMay 22, 2024 · In the plug flow the diameters of the bubbles are smaller than the tube. Slugs are similar in dimension to the tube diameter. The slugs travel at a speed that is a substantial fraction of the gas velocity and occur intermittently. Since these large gas slugs are separated from one another by slugs of liquid, they cause large pressure and liquid ... WebFlow patterns and the use of aIr eliminators Slug flow condition: The most common two-phase flow regime is called slug flow, in which the pipe cross section is filled alternatively with gas and liquid.
