The immersed boundary method [PDF]
Acta Numerica, 2002 This paper is concerned with the mathematical structure of the immersed boundary (IB) method, which is intended for the computer simulation of fluid–structure interaction, especially in biological fluid dynamics. The IB formulation of such problems, derived here from the principle of least action, involves both Eulerian and Lagrangian variables ...

Pressure boundary conditions for immersed-boundary methods. [PDF]
J Comput Phys, 2023 Immersed boundary methods have seen an enormous increase in popularity over the past two decades, especially for problems involving complex moving/deforming boundaries. In most cases, the boundary conditions on the immersed body are enforced via forcing functions in the momentum equations, which in the case of fractional step methods may be problematic

A face-based immersed boundary method for compressible flows using a uniform interpolation stencil
Frontiers in Mechanical Engineering, 2022 In this study, an immersed boundary method developed for compressible viscous flows (Ramakrishnan, R., Girdhar, A., & Ghosh, S. (2016). Immersed Boundary Methods for Compressible Laminar Flows) is modified to improve their stability and robustness ...

Immersed Boundary Methods: Historical Perspective and Future Outlook
Annual Review of Fluid Mechanics, 2022 Immersed boundary methods (IBMs) are versatile and efficient computational techniques to solve flow problems in complex geometric configurations that retain the simplicity and efficiency of Cartesian structured meshes. Although these methods became known

Immersed boundary conditions for moving objects in turbulent flows with the lattice-Boltzmann method
The Physics of Fluids, 2021 An immersed boundary method is coupled to a turbulent wall model and Large Eddy Simulation, within the Lattice-Boltzmann framework. The method is able to handle arbitrarily moving objects immersed in a high Reynolds number flow and to accurately capture ...
