Description

The air flow distribution and the contaminant diffusion field in a conventional-flow-type clean room with flow obstacles in various arrangements are analysed by means of model experiments and three-dimensional numerical simulations. Correspondence between the simulations and the experiments is fairly good, both the velocity field and for the contaminant diffusion field. On the basis of this validated procedure, further analyses of the air flow in a clean room with flow obstacles variously arranged are conducted by means of numerical simulations based on the k-epsilon turbulence model. From these analyses, much useful information is obtained concerning the velocity field and the contaminant diffusion field around obstacles and also concerning the influence of flow obstacles on the entire flow field.

KEYWORDS: clean rooms, air pollution, contaminants, indoor, air flow, particles, experiment, calculating, air quality.
