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.

Void Fractions in Subcooled Flow Boiling
Journal of Heat Transfer, 1969A semianalytic model is presented for the prediction of void fractions in subcooled flow boiling at elevated pressures. The model is based on the formation and growth of a bubble boundary layer adjacent to the heated surface at a rate determined by the difference between the imposed surface heat transfer and the heat removal capability of the subcooled

Critical Heat Flux in Subcooled Flow Boiling
Proceeding of International Heat Transfer Conference 11, 1998This chapter reports a survey of recent experimental work performed to obtain parametric trends of critical heat flux (CHF) in water-subcooled flow boiling, with special concern for high liquid velocity and subcooling, small-diameter channels, and low-intermediate pressure, together with a review of current modeling analysis.

Effects of turbulence and secondary flows on subcooled flow boiling
Heat and Mass Transfer, 2014Experiments are conducted on the influence of turbulence and longitudinal vortices on subcooled flow boiling in a vertical, rectangular channel. Different flow inserts are used to create turbulence and vortices in the channel. Studied boiling regimes range from the onset of nucleate boiling over the critical heat flux up to fully developed film boiling.

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 ...

Changes of enthalpy slope in subcooled flow boiling
Heat and Mass Transfer, 2005Void 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.

On the mechanism of subcooled flow boiling of binary mixtures
International Journal of Heat and Mass Transfer, 1994Abstract Correlations have been developed for forced convection subcooled boiling of binary mixtures using data on acetone-water, isopropanol-water and n- butanol-water systems. Separate correlations for the partial boiling region and for the fully developed boiling region incorporating the effects of degree of subcooling, liquid velocity and ...

Simulation of subcooled flow boiling in a micro-channel
International Journal of Refrigeration, 2011Bubble behavior was simulated to analyze the mechanism of subcooled boiling in a micro-channel. Bubble growth, condensation, and collapse in subcooled boiling, as well as the function of the degree of subcooling, lift-off diameter, heat flux, and mass flux are discussed.

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.
