Characteristics of rocket fuel cooling by means of liquid nitrogen in ground complex tanks equipped with heat exchange jackets

Abstract

The authors developed dedicated computational techniques and combined those with numerical simulation of heat transfer processes in ground complex tanks equipped with heat exchange jackets to discover the specifics of how rocket fuel may be cooled with liquid nitrogen used to sparge antifreeze in the cavities of the heat exchange jackets. The paper provides estimation data for rocket fuel cooling efficiency as a function of mass flow rate of liquid nitrogen for various options of setting up fuel mixing in the storage tank during cooling.
