This paper presents high spatial resolution multigrid cross-correlation digital PIV (MCCDPIV) measurements of the near jet region of a pulsed round jet. The experiments were conducted in LTRAC 1000 mm × 500 mm × 500 mm water jet facility. The jet is generated by a piston-cylinder arrangement terminating in a sharp edged orifice mounted on the wall of the facility. The piston was moved by a stepper motor controlled by a four-axis programmable controller. Two Reynolds numbers based on the orifice diameter and the mean velocity of 2000 and 4000 were investigated. The pulsing amplitude of the jet velocity corresponded to 25% of the mean velocity and the pulsing frequency was kept fixed at 1 Hz. The instantaneous MCCDPIV velocity fields were acquired through single-exposed imaging with a 4008 px × 2672 px 14 bit digital CCD.
