Modélisation d'une boucle diphasique à pompage capillaire pour utilisation spatiale
The modelling of a two-phase capillary pumped loop for use in space
Aerospatiale Espace et Défense, Cannes
This paper presents the preliminary thermal and hydraulic model of Stentor (Satellite de Télécommunication pour l'Expérimentation de Nouvelles Technologies en orbite) Capillary Pumped Loop (CPL). This multiple-evaporator two-phase ammonia loop acquires, transports and rejects heat dissipated by the Stentor Tx Antenna. The loop consists of six evaporators, six integrated-reservoirs, six capillary links, fluid transport lines and two rectilinear condensers. The validity and limitations of the modelling assumptions are presented and discussed. The CPL elements are built with the component models available in SINDA/FLUlNT thermal and fluid software code.
