Available in PDF, EPUB and Kindle. Book excerpt: In multi physics computations, where a compressible fluid is coupled with a linearly elastic solid, it is standard to enforce continuity of the normal velocities and of the normal stresses at the interface between the fluid and the solid. In a numerical scheme, there are many ways that the velocity- and stress-continuity can be enforced in the discrete approximation. This paper performs a normal mode analysis to investigate the stability of different numerical interface conditions for a model problem approximated by upwind type of finite difference schemes. The analysis shows that depending on the ratio of densities between the solid and the fluid, some numerical interface conditions are stable up to the maximal CFL-limit, while other numerical interface conditions suffer from a severe reduction of the stable CFL-limit. The paper also presents a new interface condition, obtained as a simplified charcteristic boundary condition, that is proved to not suffer from any reduction of the stable CFL-limit. Numerical experiments in one space dimension show that the new interface condition is stable also for computations with the non-linear Euler equations of compressible fluid flow coupled with a linearly elastic solid.
Download or read book Computational Methods for Fluid Dynamics written by Joel H. Ferziger and published by Springer. This book was released on 2019-08-16 with total page 596 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a guide to numerical methods for solving fluid dynamics problems. The most widely used discretization and solution methods, which are also found in most commercial CFD-programs, are described in detail. Some advanced topics, like moving grids, simulation of turbulence, computation of free-surface flows, multigrid methods and parallel computing, are also covered. Since CFD is a very broad field, we provide fundamental methods and ideas, with some illustrative examples, upon which more advanced techniques are built. Numerical accuracy and estimation of errors are important aspects and are discussed in many examples. Computer codes that include many of the methods described in the book can be obtained online. This 4th edition includes major revision of all chapters; some new methods are described and references to more recent publications with new approaches are included. Former Chapter 7 on solution of the Navier-Stokes equations has been split into two Chapters to allow for a more detailed description of several variants of the Fractional Step Method and a comparison with SIMPLE-like approaches. In Chapters 7 to 13, most examples have been replaced or recomputed, and hints regarding practical applications are made. Several new sections have been added, to cover, e.g., immersed-boundary methods, overset grids methods, fluid-structure interaction and conjugate heat transfer.

This book was released on 2015 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluid-structure interaction is a big class of research topics and many are very active. We introduce several techniques for approaching some particular fluid-structure interaction problems and some research done by the author that is relevant to these methods. The governing equations for the fluid are the Navier-Stokes equations or their limit forms, namely the Stokes equations or the Euler equations. In different regimes, different tools are needed to approach the problems. We first introduce two techniques that are widely used in the study of Stokes flows (very viscous flows). The first is a slender body theory that takes advantage of the linearity of the Stokes equations and the small aspect ratio of the filament. The obtained asymptotic equation is a 1D partial differential equation about the dynamics of the centerline of the filament. We then use the slender body theory to approach the sedimentation of a weakly flexible filament. Taking advantage of the separation of time scales, we perform a multiple scale analysis to figure out the rotation rate and sedimentation velocity. Compared with a rigid rod, the weakly flexible filament reorients as it sediments and the lateral displacement is confined. The reorientation rate we derive is then used to explore the instability of a dilute suspension of weakly flexible filaments. The flexibility has double effects on the instability of the suspension: the flexibility creates a base state that renders more instability while the direct effect of the flexibility is to suppress the instability of the perturbation. The second is the boundary integral formulation for solving swimming and sedimentation problems of bodies, including non-slender ones, numerically. For the swimming problems of rigid helical bodies, we propose a boundary integral formulation by placing rotlets along the center line and introduce a special helical coordinate system for an asymptotic analysis method. The improved asymptotic results by a boundary layer analysis compare favorably with those computed using the boundary integral formulation. Leaving the Stokes flows, we then look at the Eulerian immersed boundary method based on a local level set method, applicable at a more general Reynolds number. We propose a new level set method that involves two level set functions and a reinitialization process that preserves the interface gradient. The obtained Eulerian immersed boundary method is more stable compared with the traditional ones, with comparable costs. The limitation is that this method favors structures that have codimension one and needs further techniques in order to approach open structures (By "open", we mean the structures as manifolds have boundaries.) To complete the story, we lastly introduce some classical complex analysis techniques for inviscid flows. We summarize Wu's derivation of the analytical results for a waving plate with small amplitude in an inviscid fluid, hopefully being a starting point for approaching the interaction of two flapping wings. The useful tools, Plemelj's formulas and the Hilbert problem, are introduced.

Available in PDF, EPUB and Kindle. Book excerpt: Fluid Dynamics is one of the most important topics of applied mathematics and physics. Together with complex flows and turbulence, multiphase flows remains one of the most challenging areas of computational mechanics, and even seemingly simple problems remain unsolved to date. Multiphase flows are found in all areas of technology, at all length scales and flow regimes. The fluids involved can be compressible or incompressible, linear or nonlinear. Because of the complexity of the problem, it is often essential to utilize advanced computational and experimental methods to solve the complex equations that describe them. Challenges in these simulations include nonlinear fluids, treating drop breakup and coalescence, characterizing phase structures, and many others.This volume brings together work presented at the Fourth International Conference on Computational and Experimental Methods in Multiphase and Complex Flows. Featured topics include: Suspensions; Bubble and Drop Dynamics; Flow in Porous Media; Interfaces; Turbulent Flow; Injectors and Nozzles; Particle Image Velocimetry; Macroscale Constitutive Models; Large Eddy Simulation; Finite Volumes; Interface Tracking Methods; Biological Flows; Environmental Multiphase Flow; Phase Changes and Stochastic Modelling.
