AN INEXPENSIVE FLOW-VISUALIZATION METHOD FOR PARTICLE TRACKING VELOCIMETRY

The aim of our work is to develop a new system for measuring the orbital velocity beneath waves which is less expensive than all the systems known presently. The scheme became possible because it takes some of the special flow characteristics into account, This paper is focused on demonstrating and explaining the new flow-visualization tool that was developed until now. The technique used stores the information of multiple flow field video pictures in one single video picture. These pictures can be analyzed with known algorithms for particle tracking using binary codes but they are also a very impressive visualization of the flow.
