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.
