Year: 2000
Type: article
Abstract: In the first report, improved post-processing algorithms, which rearrange discrete velocity vectors obtained by PTV better into regular grid spaces, were proposed. The present report deals with extensions of the methods to time serial processing and to the detection of mis-matched vectors. The performance of these algorithms are evaluated by using the flow around a rectangular cylinder and a vortex flow. Furthermore, the actual advantages of using these methods are discussed by applying them to the experimental result of sudden vortex generation due to the collision of a circular cylinder with a flat wall.
