Measurement of periodic flow using micro particle image velocimetry with phase sampling technique

This paper reports a new method for measurement of periodic flows with phase-sampling technique by using conventional micro particle image velocimetry (PIV). Non-integer multiples for the laser pulse frequency and the frequency of the periodic flow are chosen such that each velocimetry data set represents a unique point in phase for the periodic flow. The method we proposed does not require precise synchronization control while still providing …
