Implicitly coupled finite volume algorithms
WitrynaThis paper presents simulations of limit-cycle oscillations of a cropped delta wing using a computational technique that implicitly couples a full Navier-Stokes solver to a linear structural solver. Computational results are compared with existing experimental measurements of the limit-cycle response of the delta wing. The limit-cycle oscillation … Witryna15 lip 2015 · We present an implicit coupling algorithm that is suitable for strongly …

WitrynaThe second approach uses only a fixed mesh, and represents the interface implicitly with some additional field. For example, this is the approach used by the Volume Of Fluid (VOF ), the Phase-Field method [8,9] and the Level-Set method (LS ).
