kinematic boundary condition

kinematic boundary condition

[¦kin·ə¦mad·ik ′bau̇n·drē kən‚dish·ən]
(fluid mechanics)
The condition that the component of fluid velocity perpendicular to a solid boundary must vanish on the boundary itself; when the boundary is a fluid surface, the condition applies to the vector difference of velocities across the interface.

Kinematic Boundary Condition on the Body/Cavity Surface.
In fact, the problem becomes a convergent one when the kinematic boundary condition is satisfied on the cavity.
Two boundary conditions must be imposed on the free surface, namely the kinematic boundary condition and the dynamic boundary condition.
For the time integration, the second-order Adams-Bashforth method is used for the Euler equations, while the Crank-Nicolson method is used for the kinematic boundary condition at the free surface.
