Iterative substructuring methods for incompressible non-isothermal flows and its application to indoor air flow simulation

The parallel solution of the incompressible Navier-Stokes equations coupled with the energy equation is considered. For turbulent flows, the k/epsilon model together with a modified wall-function concept is used. The iterative process requires the fast solution of advection-diffusion reaction and Oseen-type problems. These linearized problems are discretized using stabilized finite element methods. We apply a coarse-granular iterative substructuring method which couples the subdomain problems via Robin-type interface conditions. Then we apply the approach to the simulation of indoor air flow problems. Copyright (C) 2002 John Wiley Sons, Ltd.
