Heat Transfer Characteristics of Turbulent Flow in a Square Channel With Angled Discrete Ribs Conference Paper uri icon

abstract

  • Experiments have been conducted to study the turbulent heat transfer and friction for fully developed flow of air in a square channel in which two opposite walls are roughened with 90 full ribs, parallel and crossed full ribs with angles-of-attack () of 60 and 45, 90 discrete ribs, and parallel and crossed discrete ribs with = 60, 45, and 30. The discrete ribs are staggered in alternate rows of three and two ribs. Results are obtained for a rib height-to-channel hydraulic diameter ratio of 0.0625, a rib pitch-to-height ratio of 10, and Reynold numbers between 10,000 and 80,000.
