Heat Transfer in an Evaporating Extended Meniscus in Capillary Tubes Utilizing Binary Fluid Mixtures
ABSTRAKT
The deformation of a thin liquid film in the presence of a binary fluid with higher surface tension under varying temperature distributions is considered. Lubrication theory and the interfacial thermocapillary stress condition were used to yield a differential equation for the film thickness. The evaporative mass flow rate, heat flux and heat transfer coefficient were evaluated for various concentrations of the binary fluid mixture. The heat transfer rate increases as the concentration of the driver fluid in the binary mixture reaches a value of 9 %. After reaching this value of concentration, the heat transfer rate was observed to decrease.
