Abstract : An approximate method for scale-modeling inert pressurant distribution in geometrically similar enclosures is applied with length scale factors of 3.84, 6, and 23 (prototype to model) for turbulent flow conditions. Modeling correlations are best in spaces with minimal clutter (no obstructions to flow). With considerable clutter, however, correlations were considered acceptable and indicated good mixing within less than an additional injection time.
