Abstract:
Abstract This paper describes a planar Doppler velocimetry (PDV) technique that
is capable of measuring the three, instantaneous and time average components of
velocity over two spatial dimensions using a single pair of signal and reference
cameras. The three views required to obtain three-component velocity information
are guided from the collection optics to a single imaging plane using flexible
fibre imaging bundles. These are made up of a coherent array of single fibres
and are combined at one end as the input plane to the measurement head.
Measurements of the velocity field of a rotating disk are used in the
development of the technique and initial results of the instantaneous velocity
field of a jet are presented.
