Boiling incipience and convective boiling of neon and nitrogen [PDF]
Forced convection and subcooled boiling heat transfer data for liquid nitrogen and liquid neon were obtained in support of a design study for a 30 tesla cryomagnet cooled by forced convection of liquid neon.

Assessment of CTF boiling transition and critical heat flux modeling capabilities using the OECD/NRC BFBT and PSBT benchmark databases [PDF]
The need to refine models for best-estimate calculations, based on good-quality experimental data, has been expressed in many recent meetings in the field of nuclear applications.

Phase appearance or disappearance in two-phase flows [PDF]
This paper is devoted to the treatment of specific numerical problems which appear when phase appearance or disappearance occurs in models of two-phase flows. Such models have crucial importance in many industrial areas such as nuclear power plant safety

Influence of heat input waveform on transient critical heat flux of subcooled water flow boiling in a short vertical tube [PDF]
The transient critical heat fluxes (CHFs) of the subcooled water flow boiling for ramp-wise heat input [Q = αt, α = 6.21 × 108 to 1.63 × 1012 W/m3 s, (q 1.08 × 107 to 6.00 × 107 W/m2)] and stepwise one [Q = Qs, Qs = 0 W/m3 at t = 0 s and Qs = 2.95 × 1010

Flow of vapour in a liquid enclosure [PDF]
A solution is developed for the flow of a vapour in a liquid enclosure in which different portions of the liquid wall have different temperatures. It is shown that the vapour pressure is very nearly uniform in the enclosure, and an expression for the net

Numerical simulation of subcooled boiling in a vertical pipe with twisted tape inserts [PDF]
Subcooled flow boiling occurs in many industrial applications and it is characterized by a large heat transfer coefficient. In this paper, numerical simulation of subcooled flow boiling in a vertical pipe is investigated by ANSYS CFX 14.
