Abstract: | The granular temperature and pressure underpins the kinetic theory of granular flows while they also playing an increasing role in other context such as modeling heat transfer, segregation, erosion, attrition and aggregation in various granular processing technologies. The validation of these theories demands experimental determination of these quantities. Diffusing wave spectroscopy (DWS) is a well established technique for measurement of granular temperature in dense granular systems. Using the dense kinetic theory expression, we derive the granular pressure from DWS data for the first time. The determined mean granular pressure variation with solid volume fraction in a liquid fluidized bed is compared with theoretical and simulation models as well as with previous experimental results. Additionally, we report axial granular pressure profiles at several solid volume fractions. |
