- In multiphase flow, large bubbles of the lighter phase that form by coalescence of small bubbles under certain conditions of fluid flow. The large bubbles occur during slug flow and plug flow. The term is named after G.I. Taylor.Reference:Davies RM and Taylor G: The Mechanics of Large Bubbles Rising Through Liquids and Through Liquids in Tubes, Proceedings of the Royal Society of London, Series A. 200 (February 22, 1950): 375-390.
