TLDR
In this article, the authors derived the maximum and minimum heat-transfer rates in the nucleate and the film-boiling regimes, respectively, using the classical results of Helmholtz Kelvan and Rayleigh expressions.Abstract:
Boiling heat transfer in the nucleate region is reviewed The transition film-boiling region is analyzed by considering the stability of a plane vortex sheet separating two inviscid fluids Using the classical results of Helmholtz Kelvan and Rayleigh expressions have been derived that predict the maximum and minimum heat-transfer rates in the nucleate and the film-boiling regimes, respectively The model exhibits the essential features of the phenomenon and shows good agreement with experimental data (auth)read more

Modifications to the MELCOR code for application in fusion accident analyses
TL;DR: In this paper, the Fusion Safety Program at the Idaho National Engineering and Environmental Laboratory (INEEL) has modified the MELCOR code in order to assess safety issues associated with loss of cooling accidents (LOCAs) and loss-of-vacuum accidents (LOVAs) in the international thermonuclear experimental reactor (ITER) engineering design activity (EDA).
