Abstract
Boiling has many applications in the field of nuclear energy, refrigeration, microelectronic and aerospace. In the boiling, study of bubble dynamics is very important due to its complexity and its direct effect on the design of heat transfer equipment. Bubble collapse is an important and very complex phenomenon of the bubble dynamics. Bubble collapse occurs only in subcooling boiling, in which bubbles are surrounded by subcooled water. The degree of subcooling significantly affects the rate of bubble collapse .When a bubble collapses, it release high thermal energy from bubble to liquid. This particular aspect of bubble collapse is also utilized in cavitation reactors, which requires a very temperature. However, this energy transfer during bubble collapse creates a number of instability phenomena in the boiling channel and affects the interfacial heat transfer coefficient. It is noted that literature lacks steady state analysis of oscillating bubble collapse. In this paper, the authors report the steady-state analysis and the bifurcation analysis of bubble collapse at a pressure of 1.0 atm. Copyright © American Institute of Chemical Engineers.
