Lecture 6 - Boundary Conditions Applied …
Lecture 6 - Boundary Conditions Applied Computational Fluid Dynamics Instructor: Andr Bakker Andr Bakker (2002-2006). Fluent Inc. (2002). 1. Outline Overview. Inlet and outlet boundaries. Velocity. Pressure boundaries and others. Wall, symmetry, periodic and axis boundaries. Internal cell zones. Fluid, porous media, moving cell zones. Solid. Internal face boundaries. Material properties. Proper specification. 2. Boundary Conditions When solving the Navier-Stokes equation and continuity equation, appropriate initial Conditions and Boundary Conditions need to be Applied . In the example here, a no-slip Boundary condition is Applied at the solid wall. Boundary Conditions will be treated in more detail in this Lecture . 3. Overview Boundary Conditions are a required component of the orifice mathematical model. (interior). orifice_plate and Boundaries direct motion of flow.
5 Neumann and Dirichlet boundary conditions • When using a Dirichlet boundary condition, one prescribes the value of a variable at the boundary, e.g. u(x) = constant .
