An overview of present day thought on the very topical subject of financial stability and central banking. The papers, written by leading researchers, provide a highly informed account of contemporary policy issues and explore the legal, regulatory, managerial and economic issues that affect central banks.
In the past few years, the differential quadrature method has been applied extensively in engineering. This book, aimed primarily at practising engineers, scientists and graduate students, gives a systematic description of the mathematical fundamentals of differential quadrature and its detailed implementation in solving Helmholtz problems and problems of flow, structure and vibration. Differential quadrature provides a global approach to numerical discretization, which approximates the derivatives by a linear weighted sum of all the functional values in the whole domain. Following the analysis of function approximation and the analysis of a linear vector space, it is shown in the book that the weighting coefficients of the polynomial-based, Fourier expansion-based, and exponential-based differential quadrature methods can be computed explicitly. It is also demonstrated that the polynomial-based differential quadrature method is equivalent to the highest-order finite difference scheme. Furthermore, the relationship between differential quadrature and conventional spectral collocation is analysed.The book contains material on:- Linear Vector Space Analysis and the Approximation of a Function;- Polynomial-, Fourier Expansion- and Exponential-based Differential Quadrature;- Differential Quadrature Weighting Coefficient Matrices;- Solution of Differential Quadrature-resultant Equations;- The Solution of Incompressible Navier-Stokes and Helmholtz Equations;- Structural and Vibrational Analysis Applications;- Generalized Integral Quadrature and its Application in the Solution of Boundary Layer Equations.Three FORTRAN programs for simulation of driven cavity flow, vibration analysis of plate and Helmholtz eigenvalue problems respectively, are appended. These sample programs should give the reader a better understanding of differential quadrature and can easily be modified to solve the readers own engineering problems.
This unique professional volume is about the recent advances in the
lattice Boltzmann method (LBM). It introduces a new methodology,
namely the simplified and highly stable lattice Boltzmann method
(SHSLBM), for constructing numerical schemes within the lattice
Boltzmann framework. Through rigorous mathematical derivations and
abundant numerical validations, the SHSLBM is found to outperform
the conventional LBM in terms of memory cost, boundary treatment
and numerical stability.This must-have title provides every
necessary detail of the SHSLBM and sample codes for implementation.
It is a useful handbook for scholars, researchers, professionals
and students who are keen to learn, employ and further develop this
novel numerical method.
Lattice Boltzmann method (LBM) is a relatively new simulation
technique for the modeling of complex fluid systems and has
attracted interest from researchers in computational physics.
Unlike the traditional CFD methods, which solve the conservation
equations of macroscopic properties (i.e., mass, momentum, and
energy) numerically, LBM models the fluid consisting of fictive
particles, and such particles perform consecutive propagation and
collision processes over a discrete lattice mesh. This book will
cover the fundamental and practical application of LBM. The first
part of the book consists of three chapters starting form the
theory of LBM, basic models, initial and boundary conditions,
theoretical analysis, to improved models. The second part of the
book consists of six chapters, address applications of LBM in
various aspects of computational fluid dynamic engineering,
covering areas, such as thermo-hydrodynamics, compressible flows,
multicomponent/multiphase flows, microscale flows, flows in porous
media, turbulent flows, and suspensions. With these coverage LBM,
the book intended to promote its applications, instead of the
traditional computational fluid dynamic method.
In the past few years, the differential quadrature method has been
applied extensively in engineering. This book, aimed primarily at
practising engineers, scientists and graduate students, gives a
systematic description of the mathematical fundamentals of
differential quadrature and its detailed implementation in solving
Helmholtz problems and problems of flow, structure and vibration.
Differential quadrature provides a global approach to numerical
discretization, which approximates the derivatives by a linear
weighted sum of all the functional values in the whole domain.
Following the analysis of function approximation and the analysis
of a linear vector space, it is shown in the book that the
weighting coefficients of the polynomial-based, Fourier
expansion-based, and exponential-based differential quadrature
methods can be computed explicitly. It is also demonstrated that
the polynomial-based differential quadrature method is equivalent
to the highest-order finite difference scheme. Furthermore, the
relationship between differential quadrature and conventional
spectral collocation is analysed.
The book contains material on:
- Linear Vector Space Analysis and the Approximation of a
Function;
- Polynomial-, Fourier Expansion- and Exponential-based
Differential Quadrature;
- Differential Quadrature Weighting Coefficient Matrices;
- Solution of Differential Quadrature-resultant Equations;
- The Solution of Incompressible Navier-Stokes and Helmholtz
Equations;
- Structural and Vibrational Analysis Applications;
- Generalized Integral Quadrature and its Application in the
Solution of Boundary Layer Equations.
Three FORTRAN programs for simulation of driven cavity flow,
vibration analysis of plate and Helmholtz eigenvalue problems
respectively, are appended. These sample programs should give the
reader a better understanding of differential quadrature and can
easily be modified to solve the readers own engineering
problems.
Computational fluid dynamics (CFD) has been widely applied in a
wide variety of industrial applications, including aeronautics,
astronautics, energy, chemical, pharmaceuticals, power and
petroleum.This unique compendium documents the recent developments
in CFD based on kinetic theories, introducing flux reconstruction
strategies of kinetic methods for the simulation of complex
incompressible and compressible flows, namely the lattice Boltzmann
and the gas kinetic flux solvers (LBFS or GKFS). LBFS and GKFS
combine advantages of both Navier-Stokes (N-S) solvers and kinetic
solvers.Detailed derivations, evaluations and applications of LBFS
and GKFS, and their advantages over conventional flux
reconstruction strategies are analyzed and discussed in the
volume.The must-have reference text is useful for scholars,
researchers, professionals and students who are keen in CFD methods
and numerical simulations.
