Recent years have seen major progress in the development of equations to describe the motion of fluid-particle mixtures and their application to a limited range of problems. With rapid advances in numerical methods and computing power we are now presented with new opportunities to use direct integration of these equations in the solution of complex practical problems. However, results so obtained are only as good as the equations on which they are based, so it is essential to have a clear understanding of the underlying physics and the extent to which it is reflected properly in these equations. In The Dynamics of Fluidized Particles, first published in 2000, Jackson formulates these equations carefully and fully describes the important existing applications that serve to test their ability to predict salient phenomena. This account will be of value to both starters and established researchers in the field, and also to people interested in applying the equations to practical engineering problems.
