Abstract

Abstract

The onset of nucleate boiling （ONB） was investigated for water flowing in the annular duct which clearance is 1.2mm at the pressure range from 1.0 to 4.5MPa.The effect on ONB of some thermodynamics parameters was also analyzed. The available data dealing with sub-cooled boiling initial point of water in narrow annular clearance duct are analyzed by using regression method. The new developed correlation was obtained by considering the bilateral heating factor.
- Narrow annular clearance,
- Onset of nucleate boiling,
- Bilateral heating
