Problem of critical area of heat transfer and energy motion under liquid binary mixtures boiling
Abstract
The experimental results of the heat flux critical density studying under the unsaturated boiling of the binary mixtures of water-n-butanol and water n-pentanol within the concentrations from 0 to 100% by weight of the organic component are provided. The compositions with the maximum (peak) critical heat flux in the binary liquids under study, are determined. At that, some paradoxes in the boiling of these mixtures and in the singularities of the curve shapes qкр(х) are revealed. The comparison of the research results obtained in the area of the binary mixtures boiling with the earlier data is carried out. On the basis of this analysis, it is concluded that the critical zone of the heat transfer is connected with the existence of the thermal energy flux limit under the binary liquid mixtures boiling. The incoming energy density is limited by the environment through which it flows. This fundamental regularity established by the authors can be interpreted as a law of the energy flux limit in the environment.
