Abstract: The Monte-Carlo method is applied to study the process of formation of a coffee ring structure during drying a droplet containing suspended particles. The calculations are performed for the two-dimensional model of droplet, by accounting for the radial flow of suspended particles directed toward the line of the three-phase contact. The dependencies of the coffee ring width on the initial concentration of particles and the coefficient of radial flow are investigated. |
| Keywords: coffee ring, drying a droplet, suspended particles |
