Abstract

Experimental data on evaporation in a 9.52 mm diameter micro-fin tube and a smooth tube with similar tube diameter are presented. The data were taken at two different evaporation temperatures (6°C and 10°C, respectively). The mass flux was between 100 and 300 kg m-2s-1 and the heat fluxes were between 6 and 14 kW m-2. Data were presented in the form of quasi-local heat transfer coefficients and frictional pressure gradients. The effect of heat flux, mass flux and evaporation pressure on the heat transfer coefficients were also reported in this investigation.
