Sommerfeld radiation boundary condition
WebJan 5, 2024 · Sommerfeld boundary condition is the most common one that is based on the assumption that at long distance from the dam face, water wave can be considered as plane wave. A plane wave can be represented by an equation of the form: in which n is the normal at the truncation boundary. This represents well-known Sommerfeld radiation condition. WebIn order to take advantage of the positive points of the FEM for interior aero-acoustic problems [3][4][5][6][7], it is necessary to deal with the infinite radiation boundary …
