Characteristics of Pressure Drops in Square Channels with Twisted Tape Inserts plus Axial Interrupted Ribs
초록
Pressure drops and friction factors in square channels with twisted tape inserts plus axial interrupted ribs are investigated. Tests are performed for Reynolds numbers ranging from 8,900 to 29,000. The rib height-to-channel hydraulic diameter,
