Research Abstract |
Molecular dynamics simulations are applied to cluster nucleation in vapor phase and bubble nucleation in liquid phase. For cluster nucleation a sulfuric acid / water vapor mixture system were simulated and nucleation rate, formation free energy, and critical nucleus were estimated. We calculated a heterogeneous nucleation with a cubic seed. For bubble nucleation we estimated the nucleation rate by using two different estimations and found the minimum system size for estimating the nucleation rate.
