Application of domain decomposition methods to indoor air flow simulation

Abstract

A framework for solving the non-isothermal unsteady Reynolds-averaged Navier–Stokes equations with emphasis on applications to thermal building simulation is prescribed in this paper. Different domain decomposition techniques are used (i) for the treatment of boundary layers, (ii) for the efficient solution of the arising linear subproblems, and (iii) for coupling the indoor air flow field with the ambient. The approach is then applied to exemplary indoor air flow configurations.
