PIV Measurements of Turbulence Statistics in the Three-Dimensional Flow Over a Surface-Mounted Obstahere homogeneous directions do not exist. As in any other measuring system based on sampling, the key to the success of such procedure lies in the acquisition of a statistically large number of samples. The use of compression of digital PIV images strongly facilitates this task. In the present work,

Results show that by comparison with small s/w (less than 5), the interactions between the inner shear layer and the recirculation zone for large s/w are weaker. The initial peaks of turbulence intensities and Reynolds shear stress corresponding to the nozzle inner and outer edges tend to

Instantaneous Doppler Global Velocimetry Measurements of a Rotor Wake: Lessons Learnedade deformation is presented. The three-component Dbv system uses a single-frequency, frequency-doubled Nd:Y AG laser to obtain instantaneous velocity measurements in the flow. The PMI system uses a pulsed laser-diode bar to obtain blade bending and twist measurements at the same instant that DGV me

Wavenumber Spectrum Estimation from Irregularly Spaced Data: Application to PIV Data Processinge and hold procedure and one based on the projection slice theorem, commonly used in tomography. Each estimator is tested using simulated PTV data. Initial results indicate that these estimators have the potential to extend spectral estimates beyond the convential Nyquist limits imposed when using regularly sampled data.
