7. 宮田 一司, 森 英夫, 大石 克巳, 濱本 芳徳, Boiling Heat Transfer and Pressure Drop of a Refrigerant Flowing in a Vertical Small Diameter Tube, KAIST Kyushu University Joint Seminar, 2008.09, In the present study, experiments were performed to examine characteristics of flow boiling heat transfer and pressure drop of a refrigerant R410A flowing in a vertical copper smooth tube with 1.0 mm inside diameter. Local heat transfer coefficients were measured in a range of mass fluxes from 30 to 200 kg/(m2•s), heat fluxes from 1 to 16 kW/m2 and qualities from 0 to 1 at evaporation temperature of 10°C. Pressure drops were also measured at mass fluxes of 100 and 200 kg/(m2•s) for upward flow and of 30, 50, 100 and 200 kg/(m2•s) for downward flow and qualities from 0.1 to 0.9. Three types of flow pattern were observed in the tube: A slug, a slug-annular and an annular flow. Based on the measurements, the characteristics of frictional pressure drop, heat transfer coefficient and dryout qualities were clarified..
