Dynamics of a two-dimensional vapor bubble confined between superheated or subcooled parallel plates [PDF]
, 2010 The dynamics of a long, two-dimensional vapor bubble confined in the gap between two superheated or subcooled parallel plates is analyzed theoretically. The unsteady expansion and/or contraction of the bubble is driven by mass transfer between the liquid
