The numerical simulation of turbulent indoor-air flows is performed using iterative substructuring methods. We present a framework for coupling eddyviscosity turbulence models based on the non-stationary, incompressible, nonisothermal Navier-Stokes problem with non-isothermal near-wall models; this approach covers the k/ǫ model with an improved wall(More)
A framework for solving the nonisothermal URANS 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(More)
