AN IMPROVED PTV SYSTEM FOR LARGE-SCALE PHYSICAL RIVER MODEL被引量：10
《Journal of Hydrodynamics》2008年第6期669-678,共10页TANG Hong-wu CHEN Cheng CHEN Hong HUANG Jian-tong 
Project supported by the National Natural Science Foundation of China (Grant Nos. 50479068, 50779014);the Technological Innovation Project of Graduate students in Jiangsu Province (Grant No.1306014);the Project of "Six Talent Peak" of Jiangsu Province (Grant No. 07-A-006).
To measure the surface flow in a physical river model, an improved system of Large-Scale Particle Tracking Velocimetry （LSPTV） was proposed and the elements of the PTV system were described. Usually the tracer parti...
