Subcooled flow boiling at high heat flux

International Journal of Heat and Mass Transfer, 1985
Abstract In an experimental investigation of subcooled flow nucleate boiling of water at atmospheric pressure on stainless steel it was found that the heat transfer coefficient increased with increasing subcooling and also with increasing wall thickness over the range 0.08–0.20 mm.

Velocity Field in Turbulent Subcooled Boiling Flow

Journal of Heat Transfer, 1997
The velocity field was measured in turbulent subcooled boiling flow of Refrigerant-113 through a vertical annular channel whose inner wall was heated. A two-component laser Doppler velocimeter was used. Measurements are reported in the boiling layer adjacent to the inner wall as well as in the outer all-liquid layer for two fluid mass velocities and ...

Peculiarities of boiling in subcooled flow

Thermal Engineering, 2009
Peculiarities of heat transfer during boiling in high-velocity flow subcooled relative to the saturation temperature are analyzed. Flow structure is analyzed. Boiling in swirled flow and boiling in flow heated on one side are considered.

Turbulent Subcooled Boiling Flow—Experiments and Simulations

Journal of Heat Transfer, 2001
Experiments and simulations were carried out in this investigation of turbulent subcooled boiling flow of Refrigerant-113 through a vertical annular channel whose inner wall only was heated. The measurements used, simultaneously, a two-component laser Doppler velocimeter for the liquid velocity field and a fast-response cold-wire for the temperature ...

Population balance models for subcooled boiling flows

International Journal of Numerical Methods for Heat & Fluid Flow, 2008
PurposeThis study aims to examine both the population balance approach based on the MUltiple SIze Group (MUSIG) model and the average bubble number density transport equation (ABND) model for 3D, low pressure, gas‐liquid, subcooled boiling, vertical flows.

Vapor Phase Measurements in Subcooled Boiling Flow

Journal of Heat Transfer, 2002
Measurements of vapor fraction and bubble axial velocity were carried out in subcooled boiling flow using a newly designed two-sensor fiber-optic probe. The sensors encountered the axial motion of the vapor bubbles essentially head-on. The new measurements were more repeatable and had less scatter in the outer low vapor fraction region of the boiling ...

Hypervapotron technique in subcooled flow boiling CHF

Experimental Thermal and Fluid Science, 1993
Abstract Fusion reactor thermal hydraulics requires suitable techniques for the removal of extremely high heat fluxes, of the order of some tens of megawatts per square meter. One possible technique, the hypervapotron, to enhance the critical heat flux (CHF) in subcooled flow boiling (already characterized by high values of CHF) was studied using ...

Bubble dynamics at boiling incipience in subcooled upward flow boiling

International Journal of Heat and Mass Transfer, 2012
Abstract Bubble dynamics in water subcooled flow boiling was investigated through visualization using a high-speed camera. The test section was a vertical rectangular channel, and a copper surface of low contact angle was used as a heated surface. Main experimental parameters were the pressure, mass flux and liquid subcooling.

Vapour void fraction in subcooled flow boiling

Nuclear Engineering and Design, 1975
Abstract Experimental data on steam void fraction and axial temperature distribution in an annular boiling channel for low mass-flux forced and natural circulation flow of water with inlet subcooling have been obtained. The ranges of variables covered are: mass flux = 1.4 × 104−1.0 × 105 kg/hr m2; heat flux = 4.5 × 103−7.5 × 104 kcal/hr m2; and inlet
