Abstract:

The development of an experimental small-scale modeling technique for conducting simulations of air distribution patterns in full-sized rooms is described. The technique was applied to simulate the motion of air in a single- room survival shelter. The parameters that describe and must satisfy the principles of dynamic similarity for a comparison of convection between a model and a full-scale room were determined. The main parameters were the Grashof and Prandtl numbers of the fluid and the aspect ratio of the room. Time exposure photographs were made of the tracer to reveal fluid motion.
