Abstract

A vapour bubble grows when the wall superheat at a nucleation site reaches an initiating value. Heat flows into the growing bubble through its curved dome and through its region of contact with the superheated wall. There are unresolved questions about these processes and the effect of the bubble on heat transfer from the wall following detachment. This paper presents preliminary measurements of wall temperature variations by liquid crystal thermography on the back of a thin, electrically-heated, vertical plate during bubble growth and detachment in water at sub-atmospheric pressure. Some of the difficulties of applying liquid crystal thermography to boiling are described.
