摘要：

It is difficult for the traditional ventilation, such as general ventilation or local ventilation, to remove dusts effectively when dust source is changeable in a workshop, especially in a large space. This paper uses the software of PHOENICS, simulating stratified air distribution of three-dimension turbulence in a large space with many kinds of interference parameters. It adopts the k-epsilon model of standard turbulence, applies staggered grid and finite volume approach discrete equation analysis, and simulates for predicting indoor air distribution of isothermal jet in the large space. The comparison and analysis between the results of simulation and empirical formula show that the simulation is available to predictive the indoor air distribution. The results are useful for the optimizing the design of complex air distribution in large spaces. (C) 2004 Elsevier B.V. All rights reserved.
