• Capillary pumped heat transfer devices rarely achieve the maximum predicted heat flux. It has been suggested this is due to interfacial thermocapillary stresses arising from liquid-vapor interfacial temperature gradients. A maroscopic mathematical model predicts this can be counteracted by introducing naturally occurring concentration gradients associated with distillation in binary fluid mixtures. This is inferred from an increase in wicking height predicted with the binary fluid. An investigation of a heated, evaporating meniscus formed by a binary fluid mixture of wetting liquids in a vertical capillary tube is under investigation. Experiments are being conducted to observe the wetting characteristics of the binary fluid mixture and how they are affected by the dynamics associated with the heating of and evaporation from a meniscus.
