Numerical modeling of ventilation and air conditions systems of large sport and culture centres

One of the most promising applications of highly effective computer technology (supercomputers) is numerical simulation of complex physical and thermophysical proccesses occuring in vast areas of concert halls and sport arenas while heating, ventilating and air conditioning. According to Russian technical standarts for building construction, numerical modeling of these systems should be carried out on the stage of their design. The variety of problems and demands, lack of understanding of the physical process involved and the necessity to make genuine decisions are encountered while conducting such a work. The experience in modeling of ventilation and air conditioning systems of Bolshoi Krenlevskyi Palace concert halls and the Moscow Conservatory named after P.I. Chaikovskyi, Zaryadie Park Philarmony concert hall and a covered ice rink arena is described.
