Experimental results concerning boiling heat transfer characteristics of steam-water two phase flow in σ22×5.5mm quadruply internally ribbed carbon steel tubes and σ18 × 3mm 1Cr18Ni9Ti smooth stainless steel tubes as used in sub critical and near critical pressure regions in domestic manufactured large once-through power boilers are presented. The tests were conducted in the electrically heated high pressure steam-water two phase flow test loop of the Xi'an Jiaotong University. The test parameters for internally ribbed tubes were as follows: pressure P=19.6-22.6MPa, rate of mass flow G = 650-l750kg/m2 ·s, heat flux accross the inner tube wall q=200-610kW/m2 ·s; and those for the smooth tubes were P=l7.2-22.6MPa, G=800-2000kg/m2·s, q = 240-630kW/m2. Via of wall temperature measurements within the range of test para-meters the criterion for boiling heat transfer deterioration and the effectiveness of deterring its occurrence in internally ribbed tubes were determined. Heat transfer characteristics of a few geometrically similar tubes are compared and evaluated.
