A new technique, based on the analysis of the signature of turbulent spots on the heat flux at the wall, is used to estimate the propagation rates of naturally occurring turbulent spots in a zero pressure gradient transitional boundary layer. Experim

The operating principle of a single-stroke, compression-heated, blowdown wind tunnel is described. The facility is known as a LICH tube (a term coined by the developers of the operating technique, Drs. Oldfield, Jones, and Schultz of Oxford Universit

New, detailed flow field measurements are presented for a very large low-speed cascade representative of a high-pressure turbine rotor blade with turning of 110 degrees and blade chord of 1.0 m. Data was obtained for tip leakage and passage secondary

The characterization of combustor turbulence and flow unsteadiness in gas turbines under realistic operational conditions is of great importance to the designers of both the combustors and the downstream turbine blades. However, because of the challe
