Numerical simulations are performed for droplet impact on curved substrates considering their importance in various applications. As the dynamic contact angle is to be accurately captured in moving contact line simulations, we use a force-based method rather than specifying a static contact angle as boundary condition or using velocity based dynamic contact angle models. The approach is based on the method proposed by Malgarinos et. al. [1] for flat surfaces, and we extend it to model droplet impact on curved substrates. The model is initially validated for flat surfaces based on 2D axisymmetric simulations using the volume of fluid (VOF) method. Subsequently, the model is extended to a curved surface where the dynamic contact angle is calculated at each point of the curved surface considering the curvature as the contact line moves. The wetting force acting at the triple-phase contact line is added as a source term in the momentum equation. The overall algorithm for droplet adhesion is implemented using user-defined routines within the framework of an existing CFD solver, with adaptive mesh refinement also used due to the intensive nature of the computations. Finally, we validate the present simulations with some existing results.
