LIMITING SUPERHEATING OF ELECTRICALLY CONDUCTING LIQUIDS - HOMOGENEOUS AQUEOUS-SOLUTIONS

Limiting superheating and the initial stage of boiling of aqueous solu tions of H2SO4, HCl, KCl, NaCl, and KOH under atmospheric pressure wer e investigated by the method involving pulse Joule heating of a jet. T he main characteristics are given of the experimental setup, photograp hs of the jet at the moment of boiling of liquid, and the concentratio n dependences of the temperature of limiting superheating of the solut ions being investigated. The experimental results are compared with th e estimates based on the data on the critical points of these solution s. The value of temperature of limiting superheating of water during u niform bulk heating was derived by extrapolation to zero temperature.
