Nonlinear dynamic analysis of natural ventilation in a two-zone building : Part B : CFD Simulations

In the second part of this paper a simple two-way simulation method is implemented using CFD software to obtain the multiplicity behavior of laminar and turbulent indoor airflows in two-zone naturally ventilated buildings. The method used proved effective in detecting and isolating multiple solutions for different building geometries. The results and simulation data are expected to be useful for building ventilation design and smoke control engineering.
