Abstract:
The atomization of metastable superheated water injected into the atmosphere from a convergent-divergent nozzle at a temperature of
240–260∘С was studied experimentally. The dispersion composition of the spray jet has a bimodal character with a predominance of submicron droplets, whose proportion increases with increasing temperature and reaches 80% at the nozzle outlet at a water temperature of 260∘С. The influence of droplet coagulation on the distribution of the proportion of large droplets along the length of the spray jet was estimated.
Keywords:
superheated water, metastable state, fine spray, dispersion characteristics, bimodal distribution, spray jet, explosive boiling, two-phase flow, scattering of monochromatic radiation.
