Transport phenomena at the liquid--vapor interface of mercury using a radioactive tracer
From international synaposium on two-phase systems; Haifa, Israel (29 Aug 1971). See CONF-710836-. A unique experimental procedure is described which individually provides a determination of the condensation and evaporation coefficient under non-isothermnal conditions of the liquid-vapor phases. Employing a radioactive mercury tracer it is demonstrated that the condensation and evaporation coefficients associated with a net condensation of a tagged mercury on the surface of its flowing (initially non-radioactive) liquid phase are equal and may be less than unity. Under the non-isothermal condition, examination of the liquid and vapor temperatures with a movable thermocouple probe demonstrated that the bulk vapor temperatures exist to within less than ten mean free path lengths of the liquid surface.
