Methods for the representation of air flows in industrial buildings (Methoden zur Darstellung der Luftströmung in Fabrikhallen)

This paper gives as a posthumous tribute to Walter Dittes, a summary of his thesis prepared at the University of Stuttgart (Germany) .It describes the various air diffusion patterns that can be used (mixing ventilation, displacement ventilation or use of both in different zones), and explains how thermal plumes are treated according to the chosen pattern.A zone model is then described for the prediction of air flows and pollutants transfers between zones within the indoor space.
