Such methods include Eulerian methods (finite difference, spectral and wavelet methods) as well as Lagrangian methods (contour dynamics, vortex methods) and are used to study such topics as 2- or 3-dimensional turbulence, vorticity generation by solid bodies, shear layers and vortex sheets, and vortex .

Abstract. This book consists of two parts (a total of 12 chapters), an appendix (17 computer programs), a bibliography, and an index. Part one, entitled: The surface vorticity method for inviscid ideal flow, is comprised of six chapters: The basis of surface singularity modeling; lifting bodies, two-dimensional aerofoils and cascades; mixed-flow and radial cascades; bodies of revolution, ducts. Attention is given to recent approaches to simulating three-dimensional incompressible fluid flows using vortex methods, noting that some require only crude information, such as the vortex blobs of the two-dimensional case. The question whether such 'crude' algorithms can accurately account for vortex stretching and converge is considered. The question is answered affirmatively by constructing.

Vortex methods have emerged as a new class of powerful numerical techniques to analyze and compute vortex motion. This book addresses the theoretical, numerical, computational, and physical aspects of vortex methods and vortex motion.

for two-dimensional flows. A complete, simplified proof of convergence in two dimensions is included. Introduction. This paper continues an analysis of the accuracy and convergence of vortex methods begun earlier by the authors in [1]. The principle of such methods is to simulate inviscid, incompressible fluid flow in two or three space.

2 Description of the Method In this section, the main idea of vortex methods is outlined. We begin with the vorticity trans-port equation, an equivalent formulation of the Navier-Stokes equations in terms of vorticity.

Vortex methods have been extensively applied to reduce the dimensionality of these aerodynamic models, based on the proper estimation of the strength and distribution of the vortices in the wake. In such modelling approaches, one of the most fundamental questions is how the vortex sheets are generated and released from sharp edges.

An inviscid model of two-dimensional vortex shedding behind a square-based section is developed. The model uses a discrete-vortex approximation for the free shear layers. The motion of the shear layers is computed from the velocities of the discrete vortices, which in turn are derived through a Schwartz-Christoffel transformation of the section.

A numerical study is presented for the fully developed two-dimensional laminar flow of viscous incompressible fluid through a curved square duct for the constant curvature δ = In this paper, a spectral-based computational algorithm is employed as the principal tool for the simulations, while a Chebyshev polynomial and collocation method as secondary tools.

In recent years vortex methods have emerged as a new class of powerful numerical techniques to analyze and compute vortex motions. In this book, we bring together a set of papers under the common theme of vortex methods and vortex motion.

We begin (Chap. 1) with a review article which surveys the design and application of vortex methods.

Mathematical Methods in Physics *immediately available upon purchase as print book shipments may be delayed due to the COVID crisis. ebook access is. design of vortex algorithms for three-dimensional flow is inherently more difficult than the two-dimensional case.

In 2-D the vorticity is conserved along particle paths, whereas in 3-D the dynamics of vortex stretching is a prominent and complex phenomenon which must be reproduced by the method. The goal of this book is to present and analyze vortex methods as a tool for the direct numerical simulation of incompressible viscous flows.

Vortex methods have matured in recent years, offering an interesting alternative to finite difference and spectral methods for high resolution numerical solutions of the Navier Stokes equations. two-dimensional vortex sheet are performed by a robust and efficient numerical method with high vortex sheet, Kelvin–Helmholtz instability, point vortex method, singularity, redistribution DOI: /JPSJ 1.
