Abstract:
A method for the calculation of three orthogonal velocity components in planar
Doppler velocimetry (PDV) using four or more measured velocity components (to
the three typically used) is presented. The advantages and disadvantages are
assessed by use of a Monte Carlo simulation and experimental measurements of the
velocity field of a rotating disk. The addition of a fourth velocity component
has been shown to lead to reductions in the final errors of up to 25%. The
selection of viewing configurations for experiments is discussed by simulation
of the level of errors in measured velocity components and investigation of the
final level of errors in the orthogonal velocity components. Experimental
measurements of the velocity field of a rotating disk are presented,
demonstrating the effect of the viewing configuration on the final level of
error.
