A numerical implementation of the advection
equation is proposed to increase the temporal resolution of
PIV time series. The method is based on the principle that
velocity fluctuations are transported passively, similar to
Taylor’s hypothesis of frozen turbulence. In the present
work, the advection model is extended to unsteady threedimensional
flows. The main objective of the method is that
of lowering the requirement on the PIV repetition rate from
the Eulerian frequency toward the Lagrangian one.
