Abstract

A study of two-phase flow and heat transfer in a small tube of 1 mm internal diameter has been conducted experimentally as part of a wider study of boiling in small channels. R141b has been used as the working fluid. The boiling heat transfer in the small tube has been measured over a mass flux range of 300-2000 kg/m² s and heat flux range of 10-1150 kW/m². In this paper the boiling map for a mass velocity of 510 kg/m² s and heat flux of 18-72 kW/m² is discussed and the problems of determining heat transfer coefficients in small channels are highlighted.
