Monte Carlo simulation of colloidal particles dynamics in a drying drop.

摘要: The work is devoted to particles dynamics simulation in a colloidal drop, when it dries on substrate and the triple-phase boundary fixed. Experimental observations [Deegan R. D. et. al., 2000] show ring deposition solid after full droplet desiccation. This phenomenon of macrolevel known as coffee effect. There are other experiments that co-effect at microlevel. We talking about formation quasicrystalline structure outer part occurrence amorphous inner zone [Mar\'{\i}n \'A.

It probably necessary take into account additional system, for example, surface tension.
