Abstract
In this study, similitude modeling for predicting room air motion was investigated theoretically and experimentally with full- and one-fourth-scale test rooms. The critical Archimedes number, at which the diffuser air jet fell immediately after entering the room, was found to decrease when the room dimensions decreased. A new scaling method was proposed based on the relative deviation of Archimedes number from its critical value.v
