Transient behavior of particle deposition in granular media under various surface interactions

摘要

Transient behavior of particle deposition in granular media arises from time-dependent changes of local particle deposition rates throughout the media. Many variables may affect the transient behavior. A system of equations describing the transient deposition phenomenon was derived by considering collector-particle and particle-particle interactions separately and by including other factors such as the excluded surface effect and the re-entrainment of deposits. A numerical method for solving this system of equations was developed and sample calculation results were presented to demonstrate the utility of these equations. The results also give a clear indication of the complexity of the transient behavior df particle deposition depending upon the nature of surface interactions. (C) 2000 Elsevier Science B.V.
