Dispositif pour l’Etude de la Croissance et des Liquides Critiques (DECLIC)
DECLIC is an apparatus developed by CNES for a NASA Express rack to support the study of material growth and liquids behaviour near their critical point. It provides all subsystems required to operate an experiment dedicated insert installed on an optical bench. To date (2009), three modules have been developed.
- The Alice Like Insert (ALI), dedicated to the observation of gas-liquid transformation near the critical point of pure fluids at low (near-room) temperatures,
- The High Temperature Insert (HTI) for heat and mass transfer at high temperature and pressure,
- The ‘DSI (Directional Solidification Insert) for observation of microstructures that form at the liquid-solid interface when transparent material solidifies.
ESA has started the feasibility assessment of an additional insert dedicated to Super Critical Water Oxidation processes.
The instrument will allow observing the interaction of supercritical water in presence of a liquid or solid solute (dissolution, mixing, jet injection, cold combustion, and nucleation) through imaging and interferometric optical techniques.
The definition of scientific requirements for this insert will take place in 2009, targeting a future flight inside DECLIC or other existing facilities on board the ISS.
