Boiling heat transfer on porous single layer brass meshes

Abstract

Abstract Heat transfer enhancement has been a crucial issue in recently developed research. The article presents the possibility of increasing the heat flux values exchanged during boiling of water and ethanol on surfaces with meshes. Single layer brass meshes were tested and the results indicate a considerable potential of such structures to improve boiling heat transfer. The comparison of the experimental data with selected models indicate large differences that might be linked with different experimental conditions and sample treatment methods. Various experimental conditions found in literature concern different pressure values, various angles of heater surface inclination as well as different sources of heat (electrical heaters, laser beam, hot fluid).
