Abstract
The deformation of particle image patterns due to velocity gradients causes errors of velocity measurements and false velocity detections in PIV (Particle Image Velocimetry). A novel technique to overcome those limitations inherent in the conventional PIV by correcting the particle image pattern according to the local velocity gradients in two dimensional flows, i.e. ∂u/∂x, ∂u/∂y, ∂v/∂x and ∂v/∂y, is proposed and successfully applied to a water flow downstream of a backward facing step.
