Witryna15 mar 2024 · This paper describes a novel 2 nd order direct forcing immersed boundary method designed for simulation of 2D and 3D incompressible flow problems with complex immersed boundaries. In this formulation, each cell cut by the immersed boundary (IB) is reshaped to conform to the shape of the IB. IBs are modeled as a … WitrynaThe immersed boundary method (IBM) introduced by Peskin (1972) is widely used to solve incompressible flows in complicated time-varying domains. The IBM was extended for compressible viscous flows (de Tullio et al., 2007; Ghias et al., 2007; Palma et al., 2006). An immersed interface method was developed for elliptic equations ( …
WitrynaA novel sharp-interface level-set based immersed boundary method is applied to capture the complex geometry of the pump. An unstructured triangular mesh is used to discretize the complex surface geometry of the pump, and a ray-tracing method is employed to classify the computational domain into fluid and solid regions.
