Аннотация

Nucleate boiling is described as a relaxation phenomenon concerning the superheating of the equivalent conduction boundary layer at the heating surface due to the rapid growth of succeeding vapour bubbles on active nuclei. For instance, the theory predicts a coincidence of a maximal slowing down of bubble growth rate and departure size (resulting in a minimal heat transmission to individual bubbles: "boiling paradox") and the occurrence of a maximum nucleate boiling peak flux at the same low concentration of the more volatile component in a binary system, which can be derived from equilibrium data. This is in accordance with experimental results.
