Abstract:
... The mathematical models for the capillary-driven flow of fluids in tubes typically assume a static contact angle at the fluid–air contact line on the tube walls. However, the dynamic evolution of the fluid–air interface is an important feature during capillary rise. Furthermore, inertial effects are relevant at early times and may lead to oscillations. To incorporate and quantify the different eff ...
