Outline of Final Research Achievements

The molecular mechanism of surface tension rise with increasing temperature of self rewetting fluids which is candidate working fluid for high performance boiling heat transfer is investigated. Using all-atom molecular dynamics simulations, liquid--vapor equilibrium of 1-butanol aqueous solutions is obtained. 1-butanol aqueous solutions is typical example of self rewetting fluid. By changing temperature at constant concentration, surface tension, surface excess, and the behavior of 1-butanol molecules at the interface are studied and the relation among them is discussed.
