Abstract
A thermodynamic model is developed to predict the onset of nucleate boiling (ONB) under rapid depressurization, addressing key challenges stemming from the fact that nucleation can take place across both positive and negative pressure regions, in tensioned liquids. By introducing a normalized Jakob number and demonstrating its relation to a normalized depressurization rate (Jar=F(Σr)), the model establishes an analytical framework capable of predicting nucleation onset across a broad range of thermodynamic states (0.4File in questo prodotto:
