hydrogen-bond structure for ice crystal in nanoscale. Molecular dynamics
method is adopted to analyze the ice crystal formed by water molecules.
In the molecular dynamics analysis, Newton’s second law of motion is
applied for predictions of the motion of any molecules. Translational and
angular velocities as well as the locations of all the molecules can be
predicted at any instant when the inertial and external forces acting on the
molecules have been known. The interactive forces between any two
molecules are determined based on Carravetta-Clementi (CC) potential in
this study. The van der Waals force and the electrostatic force are
evaluated between water molecules and then the translational and angular
velocity vectors and the position of the molecules can be predicted. The
study includes: (1) the annealing of hydrogen-bond structure for ice
crystal, (2) the influence of temperature on the vibration of the molecules
within a fixed ice crystal layers, and (3) the leaping behavior of the
drifting molecules on the crystal layer surface after they impinge on the
surface at different temperatures and incident angles.
