Computational investigation of ventilation effectiveness in a paper producing industry

In this paper, the ventilation of a "crepe" paper-processing workshop conta ining dryers, which generate a high thermal load, is considered. Displaceme nt ventilation has been used for many years in industries with high thermal load. The main ventilation design problem is to find the appropriate venti lation flow that guarantees that the interface between the fresh air zone a nd the hot air zone is located above the occupied region of the room. The p aper presents a mathematical model, implemented in a general computer code that can provide detailed information on the velocity, temperature and mois ture fields in three-dimensional buildings of any geometrical complexity. The simulation results could be used as a base for further analysis for ven tilation design for other industrial processes producing high levels of the rmal loads and moisture, intending to a proper ventilation system selection for a more healthy and comfort environment in a building.
