Contact-line dynamics and damping for oscillating free surface flows
New experimental data on the frequency and damping of Faraday water waves in glass tanks are presented to demonstrate the contact-line effect on free surface flows. We find a complicated nonlinear relationship between wave frequency and amplitude near contact lines: The amplitude dispersion for decaying standing waves directly progresses from a nonlinear regime due to large amplitude to a regim...
متن کاملNumerical Simulation of Free Surface Flows and Comparison of Symmetry and Real Boundary Conditions at the Free Surface
For implementation
 of the free surface boundary condition, a new subroutine has been introduced to an existing steady 3-D body fitted code. This code was previously written for steady flow simulation in closed ducts. The algorithm used in this subroutine reduces the instability problem according to the free surface wave generation. For code validation, it was applied to two different open c...

متن کاملEffective slip law for general viscous flows over oscillating surface
We consider the non-stationary three dimensional viscous flow in a bounded domain, with the lateral surface containing microscopic surface irregularities. Under the assumption of a smooth flow in the domain without roughness, we prove that there is a smooth solution to a problem with the rough boundary. In the papers by Jäger and Mikelić the friction law was obtained as a perturbation of the Po...
متن کاملA local surface model applied to contact line dynamics
7 We consider a set of equations modeling contact line dynamics. The model consists of the Navier–Stokes free surface flow with local slip-type boundary conditions and gradient surface ten-9 sion coupled with a mesoscopic local surface model (nonlinear degenerated equations) describes the surface tension variations. The dynamical contact angle and the local surface tension variations are 11 unk...
