Investigation of condensed supercritical ethylene jets using Small Angle X-ray Scattering (SAXS) technique

The ability of the Small Angle X-ray Scattering (SAXS) technique to measure small droplets generated by the nucleation process within a highly dynamic supercritical ethylene jet both inside and outside an injector was successfully demonstrated. Droplet nucleation, droplet size distribution, droplet growth, and the dependence of droplet nucleation/condensation on flow properties can be explored with the SAXS technique.
