VENTILATING AND MIXING PROCESSES IN NONUNIFORM SHELTER ENVIRONMENTS.
Abstract
Ventilating systems for shelters can be simulated by either of two analytical models. The first, the 'isostate' model, is based on the assumption that the environment is spatially uniform. This state of uniformity can be approached only with a system that includes distribution ductwork and diffusion outlets. The second, the nonisostate or 'varistate' model, is based on the incremental transfer of metabolic heat and moisture to the air as it streams through an occupied spade. The varistate model is associated with nonuniform environments and systems that do not distribute air. Equations are derived for ventilating and mixing processes and for variable parameters. (Author)
