摘要: Abstract In this study, we develop the spatial filtering velocimetry (SFV) technique to measure velocity distribution of small spherical and irregular particle flows using a linear CCD camera. addition, energy barycentre correction algorithm is used enhance measurement accuracy. A constantly running conveyor belt test accuracy SFV system. Furthermore, distributions in rotating drum are measured demonstrate usability method granular We further discuss effect key system parameters on results measurement, optimal thresholds given paper.
