METHOD OF DESIGNING INTERNALLY RIDGED HEAT TRANSFER TUBE FOR OPTIMUM PERFORMANCE

摘要

Metal heat transfer tube has a single start helical ridge on its inner surface which conforms to a range of values of a disclosed equation relating the height of the ridge to its pitch and to the inner diameter of the tube. A method of designing a tube for maximum performance is also disclosed. The improved tube provides especially good results in systems, such as steam condensation systems, wherein a single phase fluid is carried by the tube.
