Abstract

AbstractIn this study the sudden change in the acceleration level on a free surface in a right circular cylinder is investigated numerically. The intention to describe the .uid motion encounters the difficulty modelling the moving contact‐line problem. In the numerical simulations the Navier slip boundary condition and a model for the dynamic contact angle are used. The model for the dynamic contact angle γd includes the dependence on the Capillary number as well as the contact angle hysteresis. We achieved very good agreement with experimental data.
