The majority of the cryogenic propellant storage schemes associated with long term storage aboard space vehicles incorporate multilayer insulation systems. In order to predict propellant losses during vehicle ascent and to determine the proper vent path spacing which will allow rapid depressurization of the insulation while maintaining the physical integrity of the insulation system, it is necessary to have a complete description of the flow phenomena within the insulation.
