Abstract

An automated particle image velocimeter has been constructed to determine fluid velocity fields by directly measuring particle image separations. A new image shifting technique eliminates directional ambiguity from velocity measurements. Theoretical and practical considerations in implementing the PIV system are presented. Using a simple, known flow field to investigate system performance, RMS errors of less than 0.7% of full scale are achieved, and at low seeding density fewer than 10% of velocity measurements produce bad data. Applications of system measurements to the instantaneous velocity field of an axisymmetric jet are presented.
