Cool-Down and Warm-Up of Large Powder-Insulated Dewars
Transient heat transfer phenomena related to the use of large storage containers for cryogenic liquid propellants have become increasingly important in rocket and missile technology. This paper presents a theoretical analysis of the heat transfer processes during the cool-down and the warm-up periods of such containers. The results can help a designer to select the appropriate type of insulation for ground use or for orbital storage, to predict the transient rate of heat transfer to a container during cool-down after filling, and to estimate the time required for warm-up of a cryogenic storage container.
