Computer simulation of thermal expansion of the charge of liquid nitrogen in the process of heat load

Abstract

The computer simulation model of the expansion of the liquid nitrogen charge during a heat load was created, and the Mises stress criterion was considered on the basis of theoretical and experimental data. The influence of the type of using temperature load was studied to generate calculated numerical data for creating fuel on liquid nitrogen. These studies are necessary for the formation of an additional numerical experiment to study the phase transition of liquid nitrogen to a gaseous state under conditions of a closed, and then sharply increasing (exponentially) volume, which is characterized as quasi-isobaric conditions.
