Immersed boundary法
Witryna10 sie 2007 · The current immersed boundary method removes slip and non-divergence-free components of the velocity field through a projection. The boundary force is determined implicitly without any constitutive relations allowing the present formulation to use larger CFL numbers compared to some past methods. Witryna16 kwi 2024 · The immersed boundary method (IBM), first developed by Professor Peskin, 1 is a methodology for dealing with boundary conditions at interfaces (including fluid–fluid and fluid–solid ones) based on meshes that do not conform to the shapes of the immersed boundaries or interfaces. The advantages of the IBM are manifold: …

Witrynathe immersed structure. The fiber models implemented in IB2d are described in subsequent sections. Equation (4) applies a force from the immersed boundary to the fluid through a delta-kernel integral transformation. Equation (5 ) sets the velocity of the boundary equal to the local fluid velocity, to satisfy the no-slip condition.
