Figure 3. (a) Sketch of the essential core part of the geometry of every deposition process where material is left behind by a moving CL of suspension or solution with a volatile solvent.

Relevant parameters are the radius of the CL R(t), height of the droplet at the center H(t), contact angle θ(t), evaporation rate J(r, t) and profile of liquid-vapor interface h(r, t).
