Curvilinear immersed boundary method for simulating fluid structure interaction with complex 3D rigid bodies
TL;DR: Numerical experiments for fluid structure interaction (FSI) problems involving complex 3D rigid bodies undergoing large structural displacements suggest that both the properties of the structure and local flow conditions can play an important role in determining the stability of the FSI algorithm.

Drag law for monodisperse gas–solid systems using particle-resolved direct numerical simulation of flow past fixed assemblies of spheres
TL;DR: In this article, the particle-resolved direct numerical simulation (DNS) results of interphase momentum transfer in flow past fixed random assemblies of monodisperse spheres with finite fluid inertia using a continuum Navier-Stokes solver are reported.

A sharp-interface immersed boundary method with improved mass conservation and reduced spurious pressure oscillations
Jung Hee Seo,Rajat Mittal +1 more
TL;DR: The proposed cut-cell based approach to reducing spurious pressure oscillations observed when simulating moving boundary flow problems with sharp-interface immersed boundary methods is shown to retain all the desirable properties of the original finite-difference based IBM while at the same time, reducing pressure oscillation for moving boundaries by roughly an order of magnitude.
Journal ArticleDOI
A smoothing technique for discrete delta functions with application to immersed boundary method in moving boundary simulations
TL;DR: It has been shown that the smoothed discrete delta functions constructed in this paper have one-order higher derivative than the regular ones, which can effectively suppress the non-physical oscillations in the volume forces and improve the accuracy of the immersed boundary method with direct forcing in moving boundary simulations.

Fronts propagating with curvature-dependent speed: algorithms based on Hamilton-Jacobi formulations
Stanley Osher,James A. Sethian +1 more
TL;DR: The PSC algorithm as mentioned in this paper approximates the Hamilton-Jacobi equations with parabolic right-hand-sides by using techniques from the hyperbolic conservation laws, which can be used also for more general surface motion problems.

On the identification of a vortex
Jinhee Jeong,Fazle Hussain +1 more
TL;DR: In this article, the authors propose a definition of vortex in an incompressible flow in terms of the eigenvalues of the symmetric tensor, which captures the pressure minimum in a plane perpendicular to the vortex axis at high Reynolds numbers, and also accurately defines vortex cores at low Reynolds numbers.

Atmosphere-Ocean Dynamics
TL;DR: In this article, the authors describe how the Ocean-Atmosphere system is driven by transfer of properties between the atmosphere and the ocean. But they do not consider the effects of side boundaries.

A multigrid tutorial
TL;DR: This paper presents an implementation of Multilevel adaptive methods for Algebraic multigrid (AMG), a version of which has already been described in more detail in the preface.
