FILTRATION FLOW IN POROUS CERAMIC FILTERS

摘要

One-dimensional steady filtration flow model in porous ceramic filter is established. With this model, the numerical calculation is carried out for cylindric and conical ceramic filter element. Along axial direction of filter element, the distribution of pressure drop, velocities both in ceramic tube and porous ceramic wall are obtained. Beside the better artifactitious compared with the cylindric ceramic filter element., the results of numerical simulation show that the conical ceramic filter element has less pressure drop, uniform velocity and more feasible distribution both of pressure and velocity along axial direction.
