  • To study the surface hydrophobicity of solid materials with the lattice Boltzmann method, a rough surface is approximately treated as simple periodic rectangular, saw-tooth and semicircular protrusion structures separately. A two-phase lattice Boltzmann model is used to simulate the change of surface hydrophobicity by calculating the contact angle of a droplet on the rough surface. Finally, the fluid flow in a nano-channel with rough walls is studied.

Abstract: To study the surface hydrophobicity of solid materials with the lattice Boltzmann method, a rough surface is approximately treated as simple periodic rectangular, saw-tooth and semicircular protrusion structures separately. A two-phase lattice Boltzmann model is used to simulate the change of surface hydrophobicity by calculating the contact angle of a droplet on the rough surface. Finally, the fluid flow in a nano-channel with rough walls is studied.
