Résumé

Two-phase flow boiling of propane has been characterized utilizing an experimental test facility. The effect of heat flux, mass flux and saturation temperature were studied on the heat transfer coefficient and pressure drop. Test conditions were mass flux from 250 to 525 kg.m-2.s-1, saturation temperature from -0.5°C to 9.5°C, heat flux from 16 to 61 kW.m-2. A smooth copper tube with internal diameter of 4.1 mm and test section length of 0.5 m was used. Experimental results show an increase of heat transfer coefficient and pressured drop with mass flux, heat flux and vapor quality before dryout. Correlations were able to predict pressure drop accurately while heat transfer coefficient was under predicted.
