WebMar 5, 2024 · It can be noticed that the boundary conditions that involve the surface tension are of the kind where the condition is given on boundary but no at a specific location. Gravity as Driving Force The body forces, in general and gravity in a particular, are the condition that given on the flow beside the velocity, shear stress (including the surface tension) and the … WebThis is the Siegert boundary condition that the resonant state has only out-going waves away from the scatterer [6, 14, 23, 27]. In fact, the Siegert boundary condition not only supports the resonant states but all other possible discrete states including the bound states and the anti-resonant states, that is, all poles of the S matrix.
