Abstract

The technique of experimental investigations of heat transfer of flat-oval tubes with incomplete transversal finning in conditions of free convection and natural draft are shown. Received results of heat exchange of single flat-oval tube with incomplete transversal finning and a single row made from such tubes are presented. Influence of transition from free convection conditions to natural draft on heat transfer is shown
