GASFLOW has been used to calculate the distribution and control of hydrogen and noxious gases in complicated nuclear containment and confinement buildings and in nonnuclear facilities. It has been applied to situations involving transporting and distributing combustible gas mixtures. It has been used to study gas behavior in complicated containment systems with low-speed buoyancy-driven flows, with diffusion-dominated flows, and during deflagrations. The effects of controlling such mixtures by safety systems can be analyzed.
