Conclusions from Heat Transfer Measurements on the Hydrodynamic Behavior of the Phase Boundary Between Two Fluids,
Abstract
Heat transfer coefficients between two fluids permit the characterization of the material transfer under the same forced convection conditions, provided that the phase boundary is clean and is covered by a film of surface-active substances, or if the phase boundary is subjected to the effect of material transfer with Marangoni stability. Such characterization is not possible in the case of boundary-surface convection free from Marangoni instability. The tests on which these conclusions are based were conducted with a special interferometer equipped with sinusoidally oscillating stirrers measuring the temperature differentials between two phases (isoamyl alcohol/water, cyclohexanol/water, cyclohexane/water, and carbon tetrachloride/water; with saponine as the surface-active substance in some of the determinations).
