... pressure sensitive paint (PSP) technique is adopted to measure film-cooling effectiveness. Three foreign gases— N 2 for low density, CO 2 for medium density, and a mixture of SF 6 and argon for high density are selected to study the effect of coolant density. The test blade features two rows of cylindrical...

... with detailed film cooling effectiveness distributions on the flat plate obtained using a steady state, pressure sensitive paint (PSP) technique. Both the flow and surface measurements were performed in a low speed wind tunnel where the freestream turbulence intensity was varied from 1.2% to 12.5...

...Lesley M. Wright; Stephen T. McClain; Michael D. Clemenson Detailed film-cooling effectiveness distributions are obtained on a flat plate using the pressure sensitive paint (PSP) technique. The applicability of the PSP technique is expanded to include a coolant-to-mainstream density ratio of 1.4...

... probes. The film-cooling effectiveness distribution is determined using the temperature-sensitive paint technique. Carbon dioxide was used as coolant to provide elevated density ratios of about 1.4. Although low thermal conductivity material is used for the endwall test plate, the measured temperature...
