Abstract

In this paper, a numerical study of a heat accumulator in the LCCP system has been carried out. The thermal and fluid-dynamic behaviour of the two-phase flow inside ducts working under cryogenic conditions as a propellant (LOX), coupled with the analysis of the phase change material (PCM) working as an accumulator element is presented. The numerical analysis is based on: i) a one-dimensional and transient integration of the governing equations for the fluid flow of propellant, and ii) a multi-dimensional and transient integration of the conservative equations in the volume occupied by the PCM, iii) the solid elements are modelled considering a multi-dimensional and transient treatment of the energy conservation equation. The numerical results of the heat accumulator analyzed are presented.
