Heat Transfer Deterioration by the Copper Oxide Layer on Horizontal Subcooled Flow Boiling
Applied Mechanics, 2023 Water–copper is one of the most common combinations of working fluid and heating surface in high-performance cooling systems. Copper is usually selected for its high thermal conductivity and water for its high heat transfer coefficient, especially in the

Influence of a Flow Obstacle on Boiling Two-Phase Flow
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 2012 In the view of the safety operation and the designing of boiling two-phase flow equipments, boiling two-phase flow characteristics, especially the critical heat flux is very important. In addition, the flow obstacle in a boiling channel, such as the spacer of boiling water reactor, influences the boiling heat transfer and flow characteristics.

Void Fraction Correlation for Boiling and Non-Boiling Vertical Two-Phase Flows in Tube [PDF]
Journal of Nuclear Science and Technology, 1976 Abstract Applicability of previously proposed Vold fraction correlation was studied on the boiling steam-water flows in tube. The correlation was found to be applicable to the data of Sekoguchi (d=13.55 mm) and Bartolomei (d=25mm), i.e. the value of parameter K in the correlation equals to unity. The average value of K for pipes of smaller diameter (d=
