摘要：
The paper presents an experimental investigation of heat transfer obtained with impinging gas jets. Lobed nozzles are tested. The study parameters are the lobe geometry, the jet Reynolds number, Re, and the normalised standoff distance, z/D. The quantitative infrared thermography associated with the thermofoil technique is applied. At high Reynolds number (Re >= 15,000)) and small normalised standoff (z/D <= 1), the three-lobe nozzle affords performance better than the other nozzles. As the normalised standoff distance increases and exceeds z/D = 7, the 4-lobe yields better performance. (C) 2011 Elsevier Masson SAS. All rights reserved.
