Available in PDF, EPUB and Kindle. Book excerpt: Experiments were conducted to determine heat transfer performance of single vertical tubes with Refrigerant-11 condensing on its outside surface. Twelve enhanced (fluted, spiraled, roped, and corrugated) tubes of 2.54-cm (1-in.) nominal outside diameter and 1.2-m (4-ft) length were tested. Several of the tested tubes featured internal enhanced geometries. A previously tested smooth tube served as the basis for comparison. Composite heat transfer coefficients (coefficients that include the resistances of both the condensing film and the tube wall), based on the total tube outside surface area, ranged from 850 to 6530 W/m2 . K (150 to 1150 Btu/h . ft2 . °F) over the heat flux range of 5675 to 31,375 W/m2 (1800 to 9950 Btu/h . ft2). The primary conclusions from this study are: (1) for a given heat flux, an external fluted tube can increase composite condensing heat transfer coefficients by up to 5.5 times the smooth tube values, giving better condensing performance than any of the other geometries tested; (2) further increase in composite condensing coefficients can be achieved by using skirts to divide the fluted tube into equal condensing lengths; and (3) for a given overall temperature difference and water flow rate, internal flutes can increase the overall performance by up to 17% over that for a tube with identical outside flutes and a smooth inside surface.

Download or read book Enhanced Condensation of R 113 on a Small Bundle of Horizontal Tubes written by and published by . This book was released on 1991 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: Condensation of R-113 was studied using an evaporator condenser test platform. The condenser section contained four horizontal tubes (nominal outer diameter 15.9 mm) forming a vertical in line column with a pitch-to-diameter ratio of 2.25 and a condensing length of 1.2m. The condenser tubes could be operated either individually (ie. as a single tube apparatus) or as a small tube bundle. This allowed investigation of the effects of condensate inundation on different types of condenser tubes. Tubes tested were smooth copper tubes, copper/nickel KORODENSE roped tubes, KORODENSE tubes wrapped with wire, and copper/nickel finned tubes (26 fpi). The outside heat transfer coefficient was calculated by experimentally determining the overall heat transfer coefficient and then using a modified Wilson Plot procedure. Great care was taken to ensure the results were not vitiated by the presence of noncondensibles. Results obtained with the smooth copper tubes are in agreement with published data and verify satisfactory operation of the test platform. Furthermore, problems associated with the apparatus encountered by previous workers were successfully overcome. In comparison to the top smooth tubes, the copper nickel top KORODENSE tube yielded about a 22% increase.
