Spline-Galerkin Solution of Dynamic Equations for Particle Comminution and Collection

摘要: The population balance equation is solved for particles undergoing a combination of growth, comminution, and collection. approximation method to use weighted Galerkin technique with cubic B-splines an implicit scheme solving the system ordinary differential equations. splines are defined on graded mesh. performance investigated by model problem simple but nonsmooth kernels. weight function chosen so that singularities in can be easily treated. A self-similar solution comminuted shown useful representation provided this over sufficiently long time interval. Stationary solutions obtained describes both particle comminution
