Numerical investigation of a dynamic contact line model for perfectly wetting liquids on a heated wall of finite conductivity
A dynamic evaporating contact line model for perfectly wetting fluids is built. This model includes the disjoining
pressure, surface tension, recoil pressure, interface resistance and viscous stress. A numerical method is used to
solve the set of equations, including the two-dimensional diffusion-convection heat transfer problem. We compute
the macroscopic contact angle and the overall evaporation heat transfer up to a fixed macroscopic length scale and
describe the governing phenomena. We found that the motion of the contact line can lead to a tremendous increase
of the local heat flux.
