LIQUID FLOW MEASUREMENTS VIA 3-D PIV

G. Papadopoulos, K. J. Hammad

Abstract

A novel approach to flow metering is described based on the particle image velocimetry technique. The flow through a round clear pipe was investigated by isolating a plane normal to the stream direction and obtaining the instantaneous velocity information of tracer particles in the plane. A stereoscopic arrangement was used to obtain all three components of velocity. Integration of the streamwise component over the cross-sectional area of the pipe gave the instantaneous flow rate through the pipe. The benefits and features of this novel approach to flow metering are discussed within the content of measurements performed at several flow rates.
