Mathematical Models of Particle Filtration

网页We have developed a size-structured continuum model of particle filtration. This consists of a set of partial differential equations that describe the evolution of the particle- and pore-size distributions. Changes in these distributions are the result of blocking, which occurs when a particle is too large to fit through a pore, and deposition

Mathematical Modelling of Deep Bed Filtration MSSANZ

网页2013年1月15日  Macroscopic models were used to predict the transient stage removal efficiency of deep bed filters. O’Melia and Ali’s model assumed that the particle removal is due to filter grains as well as the particles that are already deposited onto the filter grain. Thus, semi-empirical models were used to predict the ripening of filtration.
