AbstractCross-correlation algorithm has been widely used in experimental measurement of solids velocity. However, its reliability and validation range remain unquantified. To this end, a CFD-based "virtual error quantification" method was proposed to quantify the reliability of cross-correlation algorithm in the measurement of solids velocity in two different gas fluidization regimes, i.e., bubbling and fast fluidization regimes (BFB and FFB). It was found that the cross-correlation algorithm works quite well in the core region of FFB, but its applications in the annulus region of FFB and in BFB should be considered with great caution. Finally, the findings were delineated by solids convection-mixing mechanism based on the relative standard deviation (RSD) of solids velocity signals and solids Peclet number. The present study highlights the deficiency of the cross-correlation based solids velocity measurement in fluidization systems and addresses the need to develop better measurement methods for solids mixing dominated systems.
