最近测量了四氯化钛池沸腾实验中液-汽界面附近液相和汽相的界面温度和压力。汽相界面温度高于液相界面温度。比熵产生率随着净沸腾通量的增加而增加，温度不连续性也是如此。尽管界面上存在温度和化学势的不连续性，但当每个相的性质之间应提供物理关系时，Δsiso可以为零。熵产生速率取决于该相中存在的条件以及液-气界面附近每个相中存在的条件。
Interfacial temperatures and pressures in liquid and vapor phases near liquid–vapor interfaces in pool boiling experiment for titanium tetrachloride have been measured recently. The interfacial vapor temperature is higher than that of liquid phase. Specific entropy generation rate increases with net boiling flux, as does the temperature discontinuity. Although the discontinuities in the temperatures and the chemical potential exist across the interfaces, the Δsisocan bezerowhen a physical relation should be provided between the properties in each phase. The entropy generation rate depends on conditions existing in that phase and that in each phase near liquid–vapor interfaces.
