This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: El trabajo se divide en tres partes fundamentales. En la primera parte (capítulo 1) se tratan las ecuaciones que rigen la dinámica de fluidos, que son las de Navier- Stokes. Se presentan las adimensionalizaciones de las ecuaciones de Navier-Stokes para problemas de convección natural y convección forzada, identificando en cada caso los grupos adimensionales que rigen el problema. La segunda parte (capítulo 2 y 3) trata sobre los métodos numéricos LBM (Lattice Boltzmann Method) y FVM (Finite Volume Method). En cada caso se presentan el fundamento teórico sobre el que se basa y también su implementación a nivel esquemático. Por último, en la tercera parte (capítulo 4) se presenta la aplicación práctica (numérica) de LBM y FVM en problemas de referencia (los cuales sirven para validar nuevas herramientas de simulación). Se discuten los resultados obtenidos de ambos métodos y se comparan entre ellos. En los últimos capítulos se presentan las conclusiones (capítulo 5), el impacto medioambiental (capítulo 6), el presupuesto (capítulo 7) y también diferentes temas que son importantes pero han quedado fuera de alcance de este proyecto (capítulo 8). En los anexos se presentan los códigos fuentes de los programas.

This book was released on 2013-03-25 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2021-11-19 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book introduces the fundamentals and applications of the lattice Boltzmann method (LBM) for incompressible viscous flows. It is written clearly and easy to understand for graduate students and researchers.The book is organized as follows. In Chapter 1, the SRT- and MRT-LBM schemes are derived from the discrete Boltzmann equation for lattice gases and the relation between the LBM and the Navier-Stokes equation is explained by using the asymptotic expansion (not the Chapman-Enskog expansion). Chapter 2 presents the lattice kinetic scheme (LKS) which is an extension method of the LBM and can save memory because of needlessness for storing the velocity distribution functions. In addition, an improved LKS which can stably simulate high Reynolds number flows is presented. In Chapter 3, the LBM combined with the immersed boundary method (IB-LBM) is presented. The IB-LBM is well suitable for moving boundary flows. In Chapter 4, the two-phase LBM is explained from the point of view of the difficulty in computing two-phase flows with large density ratio. Then, a two-phase LBM for large density ratios is presented. In Appendix, sample codes (available for download) are given for users.
