In steady-state water evaporation, the local evaporation flux is found uniform before the thermocapillary convection transition at the droplet. If the thermocapillary flow is present, the local evaporation flux becomes nonuniform as a result of effects of thermal conduction from liquid and vapor phases, thermocapillary convection at interface, or the viscous dissipation after the interfacial turbulent transition. The local vapor-phase pressures predicted from statistical rate theory become nonuniform after the thermocapillary convection transition. But, the average predicted pressure agrees with the measured vapor-phase pressure.
