Presents experimental data on evaporation in a 7mm diameter microfin tube. The data were taken at three different evaporation temperatures, (2degC, 6degC and 10degC). The mass flux was between 100 and 300 kg/m2.s and the heat flux was between 7 and 12.4 kW/m2. Presents data in the form of local heat transfer and frictional pressure gradient. Reports the effect of heat flux, mass flux and pressure on the heat transfer coefficient.
