Numerical solution of a two-dimensional fluidized bed model

摘要: SUMMARY The numerical solution of a model describing two-dimensional fluidized bed is considered. takes the form hyperbolic system conservation laws with source term, coupled an elliptic equation for determining streamfunction. Operator splitting used to produce homogeneous one-dimensional systems and ordinary differential equations involving term. problems are solved using Roe’s method addition entropy fix. procedure second-order in time first-order space. Second-order-accuracy space obtained flux limiting techniques. Numerical experiments which show development bubbles presented. familiar kidney-shaped bubble, observed experimentally, found when On same mesh, produces no longer kidney-shaped. © 1998 John Wiley & Sons, Ltd.
