Stochastic dynamics of boiling on the heating element surface

Stochastic dynamics of boiling on the heating element surface Abstract Dynamics of a liquid boiling on a heating element surface is investigated for the equivalent problem of dynamics of temperature of the fuel cell obtained in the concept of boiling curve. It has been shown that the structural insta-bility of the potential of boiling curve leads to the need of studying the problem of temperature fluctuations of the surface on which boiling occurs. A theoretical analysis of the Itô's equation for the considered system model has shown that at a certain intensity of external random factors, the system passes from one state of self-organized criticali-ty to another. These processes are accompanied by 1/fα–noise (flicker-noise), which is regarded as an objective indica-tor of the boiling crisis. The theoretical results of the work have been confirmed by experimental data of other authors. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Thermophysics and Aeromechanics Springer Journals

Abstract

Abstract Dynamics of a liquid boiling on a heating element surface is investigated for the equivalent problem of dynamics of temperature of the fuel cell obtained in the concept of boiling curve. It has been shown that the structural insta-bility of the potential of boiling curve leads to the need of studying the problem of temperature fluctuations of the surface on which boiling occurs. A theoretical analysis of the Itô's equation for the considered system model has shown that at a certain intensity of external random factors, the system passes from one state of self-organized criticali-ty to another. These processes are accompanied by 1/fα–noise (flicker-noise), which is regarded as an objective indica-tor of the boiling crisis. The theoretical results of the work have been confirmed by experimental data of other authors.
