High Heat Flux Evaporation of Low Surface Tension Liquids from Nanoporous Membranes

Water is often considered as the highest performance working fluid for liquid–vapor phase change due to its high thermal conductivity and large enthalpy of vaporization. However, a wide range of industrial systems require using low surface tension liquids where heat transfer enhancement has proved c...

Description
Summary:Water is often considered as the highest performance working fluid for liquid–vapor phase change due to its high thermal conductivity and large enthalpy of vaporization. However, a wide range of industrial systems require using low surface tension liquids where heat transfer enhancement has proved challenging for boiling and evaporation. Here, we enable a new paradigm of phase change heat transfer, which favors high volatility, low surface tension liquids rather than water. We utilized a nanoporous membrane of ≈600 nm thickness and
