Experimenal simulations of adsorbed particles and relations with crystal grow

摘要

Dynamic characteristics of small water droplets which exist on hot water surface T>40 deg C were analyzed. The size of the droplets was 20-50 μm. The droplet has attractive and repulsive forces generated by thermohydrodynamic effects. These droplets showed behaviors similar to a perfect two-dimensioanl particle system. By use of thin line heater, a one-dimensional droplet array was formed. From the analysis of the distance between droplets in the array, temperature difference of the droplets and the maximumlength of the thermohydrodynamic potential were derived. From the condensation procerss into the one-dimensional array, the potential energies of the droplets were derived. The correlated motions of the droplets were observed when the structure of the droplet system transoms from one line to two lines. At least three droplets in the end of the array act as "boundary layer" in the condensation process.
