Mathematical modeling of environmental conditions inside historical buildings. The case of the archaeological museum of Athens

摘要

Indoor pollutants can damage cultural property stored in museums, art galleries and archives. A relatively small number of measurements available for the interiors are restricted to just a few gases. The paper draws attention to the lack of information about the airborne pollutants' dispersion of museum interiors and presents a mathematical model, implemented in a general computer code, that can provide detailed information on velocity and temperature as well as pollutants' concentrations prevailing in three-dimensional buildings of any geometricla complexity, for given external meteorological conditions. The model involves the partial differential equations governing flow and heat transfer, in large enclosures, containing heat and pollutants soruces.
