Thursday, October 13, 200512:00 PM - 1:00 PMCNLS Conference Room (TA-3, Bldg 1690) Seminar Gas-grain simulations: the "Quicksand-Effect" Dirk KadauUniversity of Oslo, Norway When modeling granular matter often the influence of the surrounding gas or fluid is neglected or simplicity. A simple model to couple the discrete grain dynamics to the continuous dynamics of a compressible fluid or gas is presented. As an example we investigate the quicksand phenomenon. Can one really drown in quicksand or will the buoyancy be even increased by the sand grains?
