A subcooled DNB investigation of freon-113 and its similarity to subcooled water DNB data
Nuclear Engineering and Design, 1970Abstract Subcooled DNB test data in Freon 113 vertically flowing in a uniformly heated circular tube are reported. With these data, extension by the existing scaling techniques for the CHF in the quality region to that for DNB in the subcooled region was verified.

Subcooled Flow Boiling in a Minichannel
Heat Transfer Engineering, 2009It has been considered that the dry-out is easy to occur in boiling heat transfer for a small channel, a mini or microchannel because the channel was easily filled with coalescing vapor bubbles. In the present study, the experiments of subcooled flow boiling of water were performed under atmospheric condition for a horizontal rectangular channel of ...

Transportphenomena in subcooled flow boiling
Heat and Mass Transfer, 2010Subcooled boiling has been subject of extensive research studies in the literature. So far, the approach of studying the phenomena of subcooled boiling has rather been an integral method by measuring the heat transport from the wall to the liquid and by following the growth and collapse of the bubbles.

High Efficiency Subcool Condenser
SAE International Journal of Passenger Cars - Mechanical Systems, 2013<div class="section abstract"><div class="htmlview paragraph">Sustainable reduction of the CO2 emissions of future vehicles goes hand in hand with the increase in efficiency of ancillary units. Of particular importance is the reduction of fuel consumption attributed to the vehicle's air conditioning system.

Freezing of a Subcooled Liquid Droplet
Journal of Colloid and Interface Science, 1995Abstract The freezing process of a subcooled liquid droplet occurs in two steps: • (i) A rapid return to the solid-liquid equilibrium temperature; the drop then freezes partially. • (ii) A slower step directed by the heat balance at the solid-liquid interface and the heat conduction toward this interface; the drop then freezes completely ...

Hydrogen Subcooling for Aerospace Vehicles
IEEE Transactions on Aerospace, 1963This paper discusses the ground handling system for hydrogen, subcooled to the liquid-solid state. The various phases of ground handling such as production, storage, transfer and servicing are explained. The problems to be experienced in each phase of the handling system are discussed.

Forced Convection Subcooled Boiling
2021Boiling of subcooled liquids can occur if the heating surface temperature exceeds the saturation temperature. Heat transfer coefficients in subcooled boiling are considerably higher than in single-phase convection. Many heat exchangers operate exclusively in the subcooled regime.

Highly Subcooled Boiling in Crossflow
Journal of Heat Transfer, 2001Experiments were carried out to determine the influence of fluid flow and liquid subcooling on flow boiling heat transfer of Freon-113 across horizontal tubes. The data cover wide ranges of velocity (1.5 to 6.9 m/s) and extremely high levels of liquid subcooling (29 to 100°C) at pressures ranging from 122 to 509 kPa.

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.
