Abstract : Highlights • There is vertical stratification within a granular medium located in a reactor. • The range of force imposed by the blade is all the lower when the speed is high. • DEM simulations give the structural rearrangement which occurs during trials. • Spatiotemporal correlations of particle motions observed by PIV could be explained by DEM.
