Abstract

Abstract

Experiment of two-phase heat transfer enhancement has been conducted in narrow rectangular channel with longitudinal vortex generators.The results show that coefficient of boiling heat transfer is more effected by mass flow flux than quality and inlet pressure.The mechanism of boiling heat transfer is changed by longitudinal vortex generators in narrow rectangular channel.Within vapor-liquid two-phase condition,the boiling heat transfer coefficient is increased by 1.1%-25.8% in narrow rectangular channel with longitudinal vortex generators.
