Abstract

Continuous-field Image Correlation Velocimetry (ICV) is an extension to the ICV technique of Tokumaru & Dimotakis (1995). The method determines the optical flow in sequences of images, and relies on a convected Lagrangian marker, e.g., a conserved scalar field, or particles, etc. The method has been applied to several simulated-flow test cases and results are presented for the error of the method, with and without noise added to the correlated test-images. The results of further tests are reported, for two laboratory flows; a NACA-0012 airfoil at high angle of attack, and a transverse jet in a coflowing stream.
