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 Δsiso can be zero when 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.
