Abstract

A numerical investigation has been carried out for the two-dimensional flow and pressure characteristics in a clean room equipped with two kinds of filters and four access panels. The distributed pressure resistance concept was applied to describe the momentum loss in filters and access panels. As a result, the velocity profile in the clean room became rather smooth by the presence of access panels. Furthermore, the average pressure drop of each access panel reached the same value so that the ratio of the flow rate should be the same at any zone. The closing of an access panel with maintaining the other access panels being opened had influenced on the velocity distribution in lower two thirds of left half space of the clean room.
