Numerical simulation of wetting on a chemically textured surface with a large intrinsic contact angle ratio by the Lattice Boltzmann Method


wetting, lattice Boltzmann method, chemically textured surfaces


In the present paper, numerical sessile tests on chemically textured surfaces in 2D and 3D are simulated. The Lattice Boltzmann method coupled with pseudo potential model is used for the simulations. A modification of the fluid-solid potential is proposed using materials’ intrinsic contact angle in order to control locally the wetting properties of a surface composed of different materials. The effect of the wetting potential and the wetting properties of chemically textured surfaces are discussed regarding to the simulations’ results and compared to some common theoretical approaches of wetting on textured surfaces.
