Deposits formed beneath bubbles during nucleate boiling of radioactive calcium sulfate solutions

Abstract

Abstract Moore and Mesler postulated microlayer evaporation beneath a bubble to explain the sudden temperature drops observed by them during nucleate boiling of water. A method was devised to estimate the microlayer thickness from the deposit formed by a series of bubbles during nucleate boiling of saturated calcium sulfate solution containing radioactive sulfur‐35. The results support the microlayer evaporation hypothesis.
