Particle Image Velocimetry
2-D image of the two fuel jets mixing (images above and below) with a swirling cross-flow of air.The average velocity vector measurements are superimposed on the average fuel mass fraction measurements.

The image above illustrates instantaneous velocity vector measurements (PIV) are superimposed on the instantaneous fuel mass fraction measurements.

PIV image taken using the sensicam digital CCD Camera System with a 5 µs interframe time.
