Changes of enthalpy slope in subcooled flow boiling

Heat and Mass Transfer, 2005
Void fraction data in subcooled flow boiling of water at low pressure measured by General Electric in the 1960s are analyzed following the classical model of Griffith et al. (in Proceedings of ASME-AIChE heat transfer conference, #58-HT-19, 1958). In addition, a new proposal for analyzing one-dimensional steady flow boiling is used.

Visual Investigation of Boiling Phenomena in CHF Subcooled Flow Boiling

1999
The present work collects the main results obtained in an experimental research carried out at the laboratories of the National Institute of Thermal-Fluid Dynamics of ENEA. A photographic study of the burnout in highly subcooled flow boiling has been performed, in order to get a detailed description of the flow pattern under different conditions of ...

Gravity effects on subcooled flow boiling heat transfer

International Journal of Heat and Mass Transfer, 2019
Abstract Subcooled flow boiling measurements using HFE-7000 were obtained in a vertical 6 mm ID sapphire tube during upward and downward flow at various gravity levels including hypergravity and microgravity. Temperature sensitive paint (TSP) applied to the inside of the tube was used to measure time and space resolved temperature and heat transfer ...

High heat flux burnout in subcooled flow boiling

Journal of Thermal Science, 1995
The paper reports the results of an experimental research carried out at the Heat Transfer Division of the Energy Department, C.R. Casaccia, on the thermal hydraulic characterization of subcooled flow boiling CHF under typical conditions of thermonuclear fusion reactors, i.e. high liquid velocity and subcooling.

Modification to Unal’s Subcooled Flow Boiling Bubble Model

Nuclear Technology, 1993
Unal's subcooled flow boiling bubble model is being used in the best-estimate light water reactor code RELAP5/MOD3. There is a significant discontinuity (by a factor of 2) in the condensation heat transfer coefficient from this model at 1 MPa, which can cause numerical problems in the code.

Subcooled Flow Boiling and Condensation

1994
Fundamental problems in two different flow regimes; subcooled water-steam bubbly condensing flow and subcooled flow boiling, in vertical conduits under low pressure and mass flux conditions, were investigated. For subcooled water-steam condensing bubbly flow, experiments were carried out to obtain a data base for the axial distribution of area-averaged
