Effects of Duct Aspect Ratio on Heat Transfer in Wavy Duct of Heat Exchanger of Gas Turbine
- 발행 : 2001.11.01
초록
The present study investigates convective heat/mass transfer and flow characteristics in wavy ducts of primary surface heat exchanger. Experiments using a naphthalene technique are carried out to determine the local transfer characteristics for flow in the corrugated wall duct. The aspect ratios of the rectangular duct cross-section are 7.3, 4.7 and 1.8 with a corrugation angle of
