Abstract

An experimental investigation of isolated acetone droplets under supercritical pressure is presented. An optically accessible pressure chamber was set up for pressures ranging up to 60 bar and temperatures of up to 530 K. A novel method for the generation of acetone droplets on demand in the vicinity of the critical point is presented. High speed shadowgraphy imaging revealed remarkable reproducibility of the droplet generation regarding their size and shape and the timing of the detachment.

The photo-physical properties of acetone in nitrogen as well as nitrogen-oxygen mixtures were investigated using planar laser induced fluorescence and phosphorescence (PLIFP). The measurements revealed a strong sensitivity and selectivity of the phosphorescence-fluorescence-ratio relative to the oxygen concentration. This demonstrates the potential of PLIFP to distinguish between the liquid and gaseous phase of acetone injected into mixtures of nitrogen and oxygen.

Keywords: Supercritical pressure; Acetone droplets; Droplet generation; Acetone fluorescence and phosphorescence; Critical point
