Extension of PIV methods

download PDFAbstract. The process of the measurement of the fluid speed by use of PIV method consists most often of several stages: the insertion of the fluid markers of movement, the stimulation of these markers to lucency, the registration of the image of markers, the quantitative analysis of registered images for the purpose of finding the parameters of their movement. Every one of these stages can be realized in many ways. This creates the possibility of adjustment of the measuring-process to realized exploratory tasks. The present article shows possibilities existing in this area, significantly transcending the offer of producers of the measuring apparatus dominant on the market. Additionally, sources of measuring errors ignored usually in manuals of commercial equipment sets are evidenced.
