All of the above categories are considered for the cases of droplets … Webb1 okt. 2024 · In this case, the contact line stays pinned when the microscopic dynamic contact angle is between a receding contact angle θ R and an advancing contact angle θ A. The most popular approach for contact angle hysteresis was developed by Spelt for a level-set method [33]. An intermediate contact angle is obtained such that the contact …
