| Summary: | but considerable enhancements were also achieved for the CIII (1.905 cm O.D.) enhanced tubes were tested. Smooth comparison. Condensation heat transfer coefficients and condenser (I m long) is used to investigate the covering the cooled surface constitutes a resistance to the electrohydrodynamically enhanced condensation heat transfer exchanged heat. heat transfer. By establishing a non uniform electric field In a condenser the thickness of the liquid condensate film in the vicinity of the condensation surface the extraction of increase the condensation heat transfer coefficient up to 5.5 is the working fluid. Korodense (3.81 cm O.D.) and Turbo Korodense tube. The necessary electric power input was found liquid from the surface can be realized. The liquid film overall UA-values are presented as a function of the applied performance on the outside surface of enhanced tubes. R-1 13 results show, for a given heat load, the Turbo CII tube can thickness is reduced and as a result the condensation heat times smooth tubes values by applying electric fields. Lower to be negligible representing less than 0.004 % of the transfer coefficient is increased. A vertical single tube tubes (3.81 cm and 1.905 cm O.D.) served as the basis for voltage for the optimum smooth tube electrode design. The |
