3.5 - Boundary Conditions for Potential Flow
Types of boundary conditions:
Kinematic Boundary Condition.
Assume ideal fluid and irrotational flow.
Assume incompressible fluid.
Velocity vector
given as the gradient of a potential function
, solution of the Laplace's equation. Is this enough information to define
?
The answer: Kinematic Boundary Condition - specify the flow velocity
at the boundaries.
Dynamic Boundary Condition.
What boundary condition is necessary for the water surface ?
Is the kinematic boundary condition on the water surface enough to specify the potential function
?
Which other type of condition we can prescribe to specify the potential function
at the water surface ?
The Dynamic Boundary Condition.
