Laboratory of short-time processes and boiling physics
The head of the laboratory is Nikitin E.D., Doctor of Physics and Mathematics.
The laboratory was created in 1973.
Laboratory staff: 11 persons, including three Doctors and four candidates of Physics and Mathematics, three post-graduate students and one engineer.
The main lines of investigations:
Evaporation in liquids under fast superheat, stretch or supersaturation with gas;
Heat transfer in processes of pulse energy excitation of a substance accompanied by explosive wall evaporation and thermal destruction;
Measurement of the fluctuation nucleation rate in the shock boiling regime;
Measurement of thermodynamic critical parameters of high-molecular substances at high temperatures;
The previously-unknown phenomenon of shock boiling-up on nuclei of fluctuation origin has been revealed. A theory unambiguously relating the value and the form of a thermal boiling-up signal in the shock regime with the liquid properties has been elaborated.
The phenomenon of explosive boiling-up of polymers by the mechanism of fluctuation origin of bubbles has been revealed.
A shock dilation wave has been discovered at fluctuation nucleation in a metastable (presonic) flow of liquid.
A study has been made of the instability of an open surface of a highly superheated liquid excited by the reaction of vapor yield.
Measurements have been made of the limiting-superheat temperatures of substances at negative pressures to Ц 10 MPa and a heating rate of 107 K/s. The phenomenon of УhealingФ of cavitation centres has been revealed.
For the first time experimental data have been obtained on the critical parameters of a number of motor fuels, marketable petroleum products, petroleum-gas systems.
New methods have been suggested for controlling explosive boiling-up by regulating fluctuation boiling centres.
