Impulse Superheating of the Solutions of Ethyl Alcohol with Water at Negative Pressures
RÉSUMÉ
We carried out an experimental study of the boiling-up of ethyl alcohol, water, and of their solutions on impulse overheating on a thin platinum wire in the field of temperatures from 100 to 310°C and negative pressures of up to −10 MPa. We obtained the dependences of the temperature of the limiting overheating of liquid over a wire on the magnitude of the negative pressure. In the case of a pure alcohol (with the concentration of 96 vol. %) the limit of the attainable overheating of liquid (Tov(P)) continually passes from the region of positive to the region of negative pressures. The additions of water into ethanol cause a discontinuity of Tov(P) in transition to negative pressures towards a decrease in the temperature of the limiting overheating of liquid.
