Abstract
We study a variety of granular flows and some models by means of a combination of simulations, experiments and analytic considerations. The models as well as the physical systems are governed by the presence of an interstitial gas. Through experimental comparison and validation of the models their applicability is determined. In particular we study bubbles of air in tubes (by experiment and simulation) the formation of stagnant zones in grain flow from a hopper (by experiment and simulation), fluidized beds (by simulation) and the intermittent flow in an hourglass (by experiment and simulation).
