dc.description.abstractEnIn the frame of the SCWO insert development aiming at studying cold combustion process in supercritical water (T < 600°C, p < 300 bar) for the recycling and valorization of wastes for long term exploration missions, we focus in here on mixing phenomena occurring within microreactors working in realistic pressure conditions (100 bar). We have considered model fluid mixtures (CO2-water diphasic and CO2-ethanol monophasic), which are representative of the future thermo-hydrodynamic properties, which will be used in SCWO with supercritical water. We have first identified new jetting mode for coflow injection, mostly driven by inertia. Then, we have determined by numerical simulation the mixing time associated with coflowing fluids inside microchannels for a monophasic system (CO2 – ethanol) at both laminar and turbulent conditions.
