| Abstract: | A numerical study combined with the field synergy principle was performed to investigate the flow and heat transfer of fully developed turbulent flow in a spirally corrugated tube.Air was selected as the working fluid and constant temperature was applied to the tube wall.Sixteen different structural parameters consisting of four different corrugation pitches and depths were considered.The effects of helical corrugation and changes of corrugation pitch and depth on field synergy performance and heat transfer... |
