Proceedings Papers

Proc. ASME. GT2020, Volume 7A: Heat Transfer, V07AT11A007, September 21–25, 2020
Publisher: American Society of Mechanical Engineers
Paper No: GT2020-15139
.... In the present study, two array impingement cooling structures with cross-flow are presented, and the heat transfer characteristics are obtained experimentally. The heat transfer performance of the impingement cooling structures are studied by using the transient liquid crystal thermography technique...

... independently to supply the inner and outer annular passages of the test rig. It allows measurements of the discharge coefficient with cross flow and co- and counter-rotating shafts with centrifugal and centripetal flow through the rotating holes. On the outer shaft, absolute and differential pressures...

Paper No: GT2010-22691
... in a rotating system, with cross-flow included and on parameters suitable for correlation of the test data. A test rig was designed to simulate shaft diameters, rotation speeds and pressure ratios typical for real gas turbine designs. The pressure ratio across the orifices varied from 1.05 to 1.5 and the Mach...
