PIVベンチマークテストの試み A Trial of Bench Mark Test for PIV
Many types of 2D-PIV system have been come onto the market, and there are various techniques for the calculation of velocity vectors. In the present paper, a bench mark test for the calculation technique of PIV was tried. Four pictured images of a real flow were distributed through internet as digital image files. The flow in the problem was that induced by an oscillating flat plate and the 2D relative flow was pictured using a CCD video camera moving with the plate. The calculation was pursued without any information on the flow. Then, the evaluated results of velocity vectors were compared with each other. The problems to utilize images of a real fluid flow as a standard image of bench mark test were also discussed.
