A Two-Stage, High-Accuracy, Finite Element Technique of the Two Dimensional Horizontal Flow Model
نویسنده
چکیده
An algorithm and essential subroutines programs are presented which implement two stage finite element Galerkin method for integrating the complete two dimensional horizontal flow model. In this method high accuracy is obtained by combining the Galerkin product with a high-order difference approximation to derivatives in the nonlinear advection operator. Program includes the use of a weighted selective lumping scheme in the finite element method, use Gauss-Seidel iterative method for solving the resulting systems of linear equations. Small scale noise was eliminated by using a Shulman filter. 1 University of Danang Danang, Vietnam [email protected], [email protected]

Numerical Simulation of the Hydrodynamics of a Two-Dimensional Gas—Solid Fluidized Bed by New Finite Volume Based Finite Element Method
n this work, computational fluid dynamics of the flow behavior in a cold flow of fluidized bed is studied. An improved finite volume based finite element method has been introduced to solve the two-phase gas/solid flow hydrodynamic equations. This method uses a collocated grid, where all variables are located at the nodal points. The fluid dynamic model for gas/solid two-phase flow is based on ...
