Prediction of the Active Nucleation Density of Heated Wall Surfaces through the Use of a Model Incorporating the Mechanism of Saturated Nucleate Pool Boiling Heat Transfer

Active nucleation density represents a major parameter in the nucleate boiling process. However, there lacks a unified method for its description. To avoid the difficulty involved in the direct measurement of the active nucleation density, the authors have proposed a prediction method with the help of a model featuring the mechanism of nucleate boiling heat transfer. The measured active nucleate size distribution curves of six types of surfaces are in good agreement with experimental results given by predecessors active in this area of research. This fully demonstrates the reliability of the above-cited model.
