S 81 Statistical properties of fluctuation boiling centers on the wall of a silylated glass cell for n-pentane near the boundary of attainable superheat [Electronic resource] / S. A. Perminov, E. V.

Рубрики: ФИЗИКА Кл.слова (ненормированные): BOILING-UP -- HETEROGENEOUS -- LIQUIDS Аннотация: High-speed video has been first used to show visually the existence of reproducible fluctuation boiling centers on a solid wall of an experimental cell for liquids superheated to the attainable superheat boundary. The main statistical characteristics of fluctuation centers have been calculated with allowance for censoring. The nonstationarity of a fluctuation process leading to the appearance of a nucleus capable of spontaneous growth has been shown. The change in the density of distribution of probabilities of boiling-up on an ensemble of centers with an increase in their number has been demonstrated. With an increase in the number of centers the probability of observation of large lifetimes of a liquid in the state of superheating decreases rapidly \\\\expert2\\NBO\\International Journal of Heat and Mass Transfer\\2013, v.57, p.429-431.pdf |
