An Immersed Boundary Method for Two-fluid Mixtures. [PDF]

open access: yesJ Comput Phys, 2014
We present an Immersed Boundary method for interactions between elastic boundaries and mixtures of two fluids. Each fluid has its own velocity field and volume-fraction. A penalty method is used to enforce the condition that both fluids' velocities agree with that of the elastic boundaries.

Removing the Stiffness of Elastic Force from the Immersed Boundary Method for the 2D Stokes Equations [PDF]

open access: yes, 2008
The Immersed Boundary method has evolved into one of the most useful computational methods in studying fluid structure interaction. On the other hand, the Immersed Boundary method is also known to suffer from a severe timestep stability restriction when ...

Direct Numerical Simulation of Gas–Particle Flows with Particle–Wall Collisions Using the Immersed Boundary Method

open access: yesApplied Sciences, 2018
We investigated particulate flows by coupling simulations of the three-dimensional incompressible Navier–Stokes equation with the immersed boundary method (IBM). The results obtained from the two-way coupled simulation were compared with those of the one-

Computing viscous flow along a 2D open channel using the immersed interface method

open access: yesEngineering 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 ...

Computational modeling and analysis of flow-induced vibration of an elastic splitter plate using a sharp-interface immersed boundary method [PDF]

open access: yesSN Applied Sciences, 2020
We present the development and benchmarking of an in-house fluid–structure interaction (FSI) solver. An implicit partitioned approach is utilized to couple a sharp-interface immersed boundary method-based flow solver and a finite-element method-based ...

Extension of the unified interpolation stencil for immersed boundary method for moving boundary problems

open access: yesJournal of Fluid Science and Technology, 2018
As an extension of the immersed boundary method with unified interpolation stencil (Kor, Badri Ghomizad, and Fukagata, J. Fluid Sci. Technol., Vol. 12, 2017, JFST0011), we propose an immersed boundary method that can handle moving boundary problems with ...

A Multi-Fidelity Framework for Wildland Fire Behavior Simulations over Complex Terrain

open access: yesAtmosphere, 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

open access: yesFluids, 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)
