Vorhersage und Analyse natürlicher Lüftungsvorgänge

R. Gritzki, W. Richter, M. Rösler

Abstract: The computational prediction of natural ventilation is often raising difficulties because of problematic boundary conditions and the unsteady nature of the flow. In addition, the pure ventilation process only delivers a part of information, for instance in case of night ventilation for cooling purposes. Using the possibilities of a special stabilized FEMcode one is able to find formulations for boundary conditions, which are very useful for the simulation of natural ventilation problems. Furthermore we present some criteria and possibilities for the analysis of transient ventilation tasks from the energetic and the hygienic point of view.
