Benchmarking the Immersed Boundary Method for Viscoelastic Flows. [PDF]
J Comput PhysWe present and analyze a series of benchmark tests regarding the application of the immersed boundary (IB) method to viscoelastic flows through and around non-trivial, stationary geometries. The IB method is widely used for the simulation of biological fluid dynamics and other modeling scenarios where a structure is immersed in a fluid. Although the IB

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

The volume-filtering immersed boundary method
Journal of Computational Physics, 2023 We present a novel framework to deal with static and moving immersed boundaries (IB). In this strategy, called Volume-Filtering Immersed Boundary (VFIB) method, transport equations are derived by filtering the Navier-Stokes equations and accounting for stresses at the solid-fluid interface.

A three-dimensional immersed boundary method for non-Newtonian fluids
Theoretical and Applied Mechanics Letters, 2018 : Fluid-structure-interaction (FSI) phenomenon is common in science and engineering. The fluid involved in an FSI problem may be non-Newtonian such as blood. A popular framework for FSI problems is Peskin's immersed boundary (IB) method. However, most of
