Heat transfer analysis of a cryogenic vessel with built-in assembly.

Résumé

The heat transfer to a cryostat equipped with a suspended assembly with liquid evaporation was described. The whole role was solved by a two-stage integration in length and time by a finite element method. The distribution of thermal bridges (inner receptacles and intakes) to intervals of unequal length, comprising dimensionally and materially homogeneous elements. For quasi-stationary points of the liquid height, the integration of thermal resistances along the length of the assembly and of the container inner vessel was carried out. The heat flow is divided into the heat for increase of temperature of the elements of the assembly and into evaporation of the differential quantity of liquid. The results were compared with the measured values on the
alternative medium, liquid nitrogen. The work is important for modelling of the function of the LNG vehicle fuelling station technology.
