Abstract
A review of the methods of heat transfer enhancement in transversely finned tubes is made. Two types of enhanced heat transfer surfaces – tubes with fins bent in the form of a confuser and flat-oval tubes with incomplete finning are proposed. The results for heat transfer and drag of such surfaces by varying geometric and performance characteristics are presented. It is shown that the use of the surfaces of the proposed types enables one to substantially decrease the metal content and sizes of heat transfer equipment.
