Immersed solid method
Witryna7 paź 2024 · A computational fluid dynamics-discrete element-immersed boundary method (CFD-DEM-IBM method) was developed for Cartesian grid simulation of the hydrodynamics and heat transfer of compressible gas–solid flow, where the interaction of gas and complex geometries was modeled using the IBM. Witryna22 gru 2005 · In this paper, we propose an immersed solid system (ISS) method to efficiently treat the fluid–structure interaction (FSI) problems. Augmenting a fluid in the moving solid domain, we introduce a volumetric force to obtain the correct dynamics for both the fluid and the structure. We further define an Euler–Lagrange mapping to …
