Projection Methods for Mathematical Modeling of Eddy Flows

摘要

An eddy incompressible gas flow is described by nonstationary Navier-Stokes equations. A Chorin-Temam projection method is used for the time integration of the nonstationary Navier-Stokes equations. A computational scheme of a discontinuous Galerkin method is applied for the H(div) finite element discretization. Mathematical modeling results of the gas flow in a channel with a variable diameter are presented. A comparative analysis of the mathematical modeling results with experimental data is given.
