SIMULATION OF THE FILTRATION OF CAST-IRON

Many structures are the result of complex interactions between various components. A simple way to simulate these interactions is to build a physical model such as the lattice gas proposed in statistical physic s : the motion of particles on a lattice is constrained by basic conse rvation laws, such as the conservation of mass and momentum. This enab les us to simulate the flow of a fluid obeying the Navier-Stokes equat ions and can be used to estimate the permeability or the coefficient o f diffusion of porous media. In the present paper, we propose lattice gas models containing a suspension to simulate aggregation and filtrat ion processes. The growth of aggregates occurs in many fields, such as in the solidification from a melt including various surface tension e ffects or the deposition of sediments. We use this model to simulate t he filtration of suspensions through a tubular-type filter.
