This book was released on 2008 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: We use a high-resolution spectral numerical scheme to solve the two-dimensional equations of motion for the flow of a uniformly stratified Boussinesq fluid over isolated bottom topography in a channel of finite depth. The focus is on conditions such that the flow is near linear resonance. The results are compared with the analytic solutions as well as experimental tank results. We also analyze the approach to breaking that occurs downstream of the topography near resonance.

Available in PDF, EPUB and Kindle. Book excerpt: The dynamics of flows in density-stratified fluids are an important topic for scientific enquiry. Flows arise in many contexts, ranging from industrial settings to the oceanic and atmospheric environments. Both the ocean and atmosphere are characterized by the basic vertical density stratification, and this feature can affect the dynamics on all scales ranging from the micro-scale to the planetary scale. This volume provides a state-of-the-art account of stratified flows as they are relevant to the ocean and atmosphere, with a primary focus on meso-scale phenomena; that is, phenomena whose time and space scales are such that the density stratification is a dominant effect, so that frictional and diffusive effects on the one hand and the effects of the earth's rotation on the other, can be regarded as of less importance. Environmental Stratified Flows is essential to researchers in the field of oceanography, coastal and marine engineering, and environmental fluid dynamics.

This book was released on 2012-12-06 with total page 585 pages. Available in PDF, EPUB and Kindle. Book excerpt: Suppose one were given the task of mapping the general circulation in an unfamiliar ocean. The ocean, like our own, is subdivided into basins and marginal seas interconnected by sea straits. Assuming a limited budget for this undertaking, one would do well to choose the straits as observational starting points. To begin with, the currents flowing from one basin to the next, over possibly wide and time-varying paths, are confined to narrow and stable routes within the straits. Mass, heat and chemical budgets for individual basins can be formulated in terms of the fluxes measured across the straits using a relatively small number of instruments. The confinement of the flow by a strait can also give rise to profound dynamical conse quences including choking or hydraulic control, a process similar to that by which a dam regulates the flow from a reservoir. The funneling geometry can lead to enhanced tidal modulation and increased velocities, giving rise to local instabilities, mixing, internal bores, jumps, and other striking hydraulic and fine scale phenomena. In short, sea straits repre sent choke points which are observationally and dynamically strategic and which contain a full range of fascinating physical processes.

Download or read book On Numerical Solutions of the General Navier Stokes Equations for Two layered Stratified Flows written by John Dzen Hwang and published by . This book was released on 1968 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this paper is to seek the general solution of the complete Navier-Stokes equations governing heterogeneous, time-dependent, incompressible, viscous, laminar fluid dynamics through digital simulation. In particular, two-layered stratified flows are treated by using a numerical algorithm called the Marker-and-Cell extended method (MACE), which is an extension of the MAC code originated by the Los Alamos Scientific Laboratory. To provide the necessary background, the paper begins with a mathematical description of stratified flows. The controlling equations are the Navier-Stokes equations, the continuity relation, and the incompressible condition. These equations and various alternative formulations are presented in axiomatic form; care has been taken in this exposition so as to exhibit the hypotheses involved in analytical hydrodynamics. Necessary boundary conditions characterizing the physical states of the stratified fluids are also stated. The finite difference scheme of MACE algorithm is discussed in detail, and specific boundary conditions are derived for the MACE code allowing inflow and outflow capabilities, no-slip and free-slip boundary-layer considerations, and free-surface formulation. In order to place the MACE method on a solid mathematical foundation, a discussion of numerous aspects of stability and error are derived for the Navier-Stokes equations. The stability of the MACE numerical scheme and the convergence of the numerical solution to the theoretical solution are proven. An example involving two-layered stratified fluid flow with inflow and outflow is presented to show how the previously non-realizable solutions of the general Navier-Stokes equations can be computed systematically through this algorithm. The example was simulated digitally to obtain movie-frames illustrating various stages of the transient state of stratified flow patterns. A complete set of flow diagrams demonstrating the logical sequence of calculations by the MACE method is provided; a FORTRAN IV program listing is appended. Natural extensions of the MACE method are proposed to handle general heterogeneous fluids of both the continuum and the discrete layered stratification. The MACE method has great potential, for continuations of this method may lead to discover whether or not viscous, laminar fluid flow can be fully described by the fundamental Navier-Stokes equations.

This book was released on 2011-10-05 with total page 1885 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mathematics of Complexity and Dynamical Systems is an authoritative reference to the basic tools and concepts of complexity, systems theory, and dynamical systems from the perspective of pure and applied mathematics. Complex systems are systems that comprise many interacting parts with the ability to generate a new quality of collective behavior through self-organization, e.g. the spontaneous formation of temporal, spatial or functional structures. These systems are often characterized by extreme sensitivity to initial conditions as well as emergent behavior that are not readily predictable or even completely deterministic. The more than 100 entries in this wide-ranging, single source work provide a comprehensive explication of the theory and applications of mathematical complexity, covering ergodic theory, fractals and multifractals, dynamical systems, perturbation theory, solitons, systems and control theory, and related topics. Mathematics of Complexity and Dynamical Systems is an essential reference for all those interested in mathematical complexity, from undergraduate and graduate students up through professional researchers.

Download or read book Solitons written by Mohamed Atef Helal and published by Springer Nature. This book was released on 2022-11-12 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: This newly updated volume of the Encyclopedia of Complexity and Systems Science (ECSS) presents several mathematical models that describe this physical phenomenon, including the famous non-linear equation Korteweg-de-Vries (KdV) that represents the canonical form of solitons. Also, there exists a class of nonlinear partial differential equations that led to solitons, e.g., Kadomtsev-Petviashvili (KP), Klein-Gordon (KG), Sine-Gordon (SG), Non-Linear Schrödinger (NLS), Korteweg-de-Vries Burger’s (KdVB), etc. Different linear mathematical methods can be used to solve these models analytically, such as the Inverse Scattering Transformation (IST), Adomian Decomposition Method, Variational Iteration Method (VIM), Homotopy Analysis Method (HAM) and Homotopy Perturbation Method (HPM). Other non-analytic methods use the computational techniques available in such popular mathematical packages as Mathematica, Maple, and MATLAB. The main purpose of this volume is to provide physicists, engineers, and their students with the proper methods and tools to solve the soliton equations, and to discover the new possibilities of using solitons in multi-disciplinary areas ranging from telecommunications to biology, cosmology, and oceanographic studies.
