Moving immersed boundary method [PDF]
International Journal for Numerical Methods in Fluids, 2017 SummaryA novel implicit immersed boundary method of high accuracy and efficiency is presented for the simulation of incompressible viscous flow over complex stationary or moving solid boundaries. A boundary force is often introduced in many immersed boundary methods to mimic the presence of solid boundary, such that the overall simulation can be ...

Hybrid finite difference/finite element immersed boundary method. [PDF]
Int J Numer Method Biomed Eng, 2017 The immersed boundary method is an approach to fluid-structure interaction that uses a Lagrangian description of the structural deformations, stresses, and forces along with an Eulerian description of the momentum, viscosity, and incompressibility of ...

Computing viscous flow along a 2D open channel using the immersed interface method
Engineering Reports, 2021 We present a numerical method for simulating 2D flow through a channel with deformable walls. The fluid is assumed to be incompressible and viscous. We consider the highly viscous regime, where fluid dynamics are described by the Stokes equations, and ...

An immersed boundary method for rigid bodies [PDF]
Communications in Applied Mathematics and Computational Science, 2016 We develop an immersed boundary (IB) method for modeling flows around fixed or moving rigid bodies that is suitable for a broad range of Reynolds numbers, including steady Stokes flow. The spatio-temporal discretization of the fluid equations is based on a standard staggered-grid approach.

A Multi-Fidelity Framework for Wildland Fire Behavior Simulations over Complex Terrain
Atmosphere, 2021 A method for the large-eddy simulation (LES) of wildfire spread over complex terrain is presented. In this scheme, a cut-cell immersed boundary method (CC-IBM) is used to render the complex terrain, defined by a tessellation, on a rectilinear Cartesian ...

Dynamic Behaviours of a Filament in a Viscoelastic Uniform Flow
Fluids, 2021 The dynamic behaviours of a filament in a viscoelastic uniform flow were investigated by an immersed boundary-lattice Boltzmann method. The effects of the Reynolds numbers (Re, ranging from 10 to 200) and the Weissenberg number (Wi, ranging from 0 to 1.2)
