“…Computed results will be compared with experimental data for C L , C D , C m , and C P from run 197R44 (see footnote **) from the National Transonic Facility test at NASA Langley Research Center. We will also compare CFD with experimental data [27] that were generated with a pressure-sensitive paint measuring technique done at the NASA Ames 11 ft transonic tunnel. As mentioned earlier, the CFD model did not include support system or tunnel walls.…”

“…This guaranteed that for every pair of images, the first image captured the rise of the luminescence and the second image captured the exponential decay of the luminescence, plus a fraction of the rise, if desired. The parameter that controls the light-camera synchronisation is the light exposure delay t L , given by : (1) where t 0 is the external trigger period, t L is the light pulse duration, is the camera signal charge transfer time of 2 s at 560 MHz readout and 5.5 s at 200 MHz readout, the optical interframing time of 100 ns being neglected. The factor f in Eq.…”

“…The traditional lifetime method using on-chip accumulation, requires multiple (~10000) pulses to accumulate enough photons on the sensor, 1 and is not compatible with a moving model. The present study demonstrates a PSP application on a moving model.…”

“…Neither measured skin friction or oil flow visualizations 16 indicated a large wing root separation bubble at 4 degrees angle of attack. Pressure-sensitive paint measurements 15 indicated the pressure distributions predicted by the computational methods without massive a separation bubble. DPW-IV included a horizontal tail for most cases, except one tail-off case for the downwash study.…”
