PT Journal AU SLEZIAK, M SO Trends in education PY 2008 BP 594 EP 597 VL 1 IS 1 DE flow visualization; particle image velocimetry (PIV) AB The results of flow visualization and digital image processing methods allowed to obtain detailed conclusions about the hydrodynamics of two-phase flow. Optical techniques of measurement, based on correlation algorithms, allow accurate determination of flow parameters. Quantitative measurements of flow and turbulence characteristics are obtained using DPIV. ER
