Dynamics of an Isolated Vapor Bubble in Saturated Nucleate Boiling : (Part 1, Bubble Growth)

抄録

As to the bubble growth in saturated pool boiling under low heat flux conditions, a theoretical equation was derived by introducing the contribution of superheated liquid around the bubble as well as that of evaporation of thin liquid film between bubble and heating surface. The theoretical prediction showed good agreement with experimental results obtained under atmospheric pressure. It was found that the contribution of surrounding liquid predominates at first and later the effect of thin film evaporation gradually happens to appear, as far as the heat flux is considerably low.
