A Thermal Stratification Model of a Cryogenic Tank at Supercritical Pressures
Storage and expulsion of cryogenic fluids at supercritical pressures has unique advantages for space applications. With the fluid at supercritical pressure in a single-phase state, the problems of separation of liquid and vapor to effect liquid transfer and feedout at zero or low g, normally associated with a subcritical storage system, are avoided. Fluid expulsion in such a system is accomplished by adding thermal energy from a heater to the stored fluid so that the tank is maintained within a nominal supercritical pressure range during the tank depletion process.
