Abstract The current research on the evaporation of ferrofluids mainly focuses characterization ultra-low vapor pressure in vacuum and theoretical analysis process. Few studies have focused experimental validation proposed rate equations comparison differences ferrofluid evaporation. In this study, based Bolotov’s model, an equation is deduced from model. study included a evaporation, magnetic ...
