Non-Isothermal Spreading of a Liquid Droplet with Dynamic Contact Angles on a Horizontal Surface

A mathematical model for an non-isothermal liquid droplet deformation with dynamic contact angles on a horizontal solid surface is presented. The main challenges such as the inclusion of the contact angle in the model, prescribing the boundary condition at the moving contact line, Marangoni convection are addressed in our model. The solution is approximated by finite elements on moving meshes with arbitrary Lagrangian Eulerian (ALE) approach. The computational results show that the heat transfer slows down the spreading rate and the maximum value of the wetting diameter
