Review of Bubble Behaviour in Pool Boiling by Single Bubble Dynamics

Investigating bubble behavior and critical heat flux in pool boiling

Abstract

Studies of bubble behaviour in pool boiling give different results at various operating conditions and parameters. To understand bubble behaviour, literature is reviewed in terms of heat flux, bubble growth, bubble release frequency, velocity, bubble departure dynamics, correlations, experimental and numerical studies at various conditions and parameters. After understanding the bubble behaviour in pool boiling this study may be beneficial for study of breaking of vapour bubble to improve the heat transfer rate by increasing critical heat flux (CHF). Breaking of bubble will be done with jet of steam or mechanistic approach to avoid blanket formation and thus enhancing critical heat flux.
