Peculiarities of boiling in subcooled flow
Thermal Engineering, 2009Peculiarities 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, 2001Experiments 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, 2008PurposeThis 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, 2002Measurements 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, 1993Abstract 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 ...

Vapour void fraction in subcooled flow boiling
Nuclear Engineering and Design, 1975Abstract 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

A correlation to predict chf in subcooled flow boiling
International Communications in Heat and Mass Transfer, 1995The present paper provides a discussion of the thermal-hydraulics requirements in fusion reactor components, with particular reference to the removal of high heat flux from plasma facing components and the critical heat flux (CHF) limit. Available experimental data on CHF of subcooled flow boiling in water, in the ranges of interest of fusion reactors ...

Critical heat flowrates in subcooled flow boiling
Thermal Engineering, 2010Matters related to calculating critical heat flowrates during boiling in a highly subcooled flow are considered. Existing data on heat transfer for swirl flow with one-sided heating are analyzed, and a formula for calculating critical heat flowrates is proposed. The conditions under which the thermodynamic limit of boiling is reached are analyzed.

Calcium sulphate scale formation during subcooled flow boiling
Chemical Engineering Science, 1997Fouling of heat transfer surfaces during subcooled flow boiling is a frequent engineering problem in process industries. Nevertheless, only few experimental and theoretical investigations on this subject can be found in the literature. In this investigation the effect of operating parameters on the deposition of calcium sulphate on heat transfer ...
