Available in PDF, EPUB and Kindle. Book excerpt: Chemical propulsion comprises the science and technology of using chemical reactions of any kind to create thrust and thereby propel a vehicle or object to a desired acceleration and speed. Cumbustion Processes in Propulsion focuses on recent advances in the design of very highly efficient, low-pollution-emitting propulsion systems, as well as advances in testing, diagnostics and analysis. It offers unique coverage of Pulse Detonation Engines, which add tremendous power to jet thrust by combining high pressure with ignition of the air/fuel mixture. Readers will learn about the advances in the reduction of jet noise and toxic fuel emissions-something that is being heavily regulated by relevant government agencies. Lead editor is one of the world's foremost combustion researchers, with contributions from some of the world's leading researchers in combustion engineering Covers all major areas of chemical propulsion-from combustion measurement, analysis and simulation, to advanced control of combustion processes, to noise and emission control Includes important information on advanced technologies for reducing jet engine noise and hazardous fuel combustion emissions

Download or read book A Scalable and Adaptive Discretization for Free Surface Incompressible Flow Simulation Using Overlapping Cartesian Grids written by Robert Elliot English and published by . This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation presents a novel method for discretizing the incompressible Navier-Stokes equations. Within numerical simulation, the underlying spatial discretization plays a crucial role in defining the properties of a numerical method. In order to resolve solution features on multiple length scales, adaptive spatial discretizations using unstructured and block structured approaches have been developed. However, while many of these methods have resolved the mathematical issues, scaling these methods to large problems which require the use of large distributed memory systems has been problematic due to issues of domain decomposition and remeshing. Block structured approaches such as Adaptive Mesh Refinement (AMR) and Chimera grid methods have been particularly successful since they allow for accurate fluid-structure interaction and spatial adaptivity. However, their scalability has been limited when applied to more complicated problems due the large number of grids required in AMR methods and the complicated linear systems arising in Chimera methods. This dissertation introduces an overlapping grid method that uses moving and overlapping Cartesian grids with independently specified cell sizes to address adaptivity. Unlike AMR approaches, by allowing the Cartesian patches to be arbitrarily rotated and translated, far fewer patches are necessary to rasterize solid boundaries and flow features. This both improves cache coherency and greatly simplifies domain decomposition. Advection is handled with first and second order accurate semi-Lagrangian schemes in order to alleviate any time step restriction associated with small grid cell sizes. The primary focus of this dissertation, however, is the Poisson discretization used in order to solve the elliptic equation for the Navier-Stokes pressure or that resulting from the temporal discretization of parabolic terms such as viscosity. A novel discretization is introduced where the coupling terms are defined implicitly through the use of a Voronoi diagram computed for a subset of the Cartesian grid cell centers. The resulting Poisson discretization is second order accurate and requires the solution of a symmetric positive definite linear system. Each aspect of the approach is demonstrated independently on test problems in order to show efficacy and convergence before finally addressing a number of common test cases for incompressible flow with stationary and moving solid bodies. The method is then extended to handle two-way coupled fluid structure interaction using a monolithic immersed boundary approach. In order to represent free surfaces the particle level set method is adapted to overlapping grids. The method includes a new treatment for particles near grid boundaries with disparate cell sizes, and strategies to deal with issues of locality in the implementation of the level set and fast marching algorithms resulting from the different bandwidths of valid values near the interface on different grids. The resulting method is capable of simulating problems with solution features on disparate scales while efficiently exploiting distributed computational resources.

This book was released on 2023-11-01 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume comprises the first part of the proceedings of the 10th International Conference on Finite Volumes for Complex Applications, FVCA, held in Strasbourg, France, during October 30 to November 3, 2023. The Finite Volume method, and several of its variants, is a spatial discretization technique for partial differential equations based on the fundamental physical principle of conservation. Recent decades have brought significant success in the theoretical understanding of the method. Many finite volume methods are also built to preserve some properties of the continuous equations, including maximum principles, dissipativity, monotone decay of the free energy, asymptotic stability, or stationary solutions. Due to these properties, finite volume methods belong to the wider class of compatible discretization methods, which preserve qualitative properties of continuous problems at the discrete level. This structural approach to the discretization of partial differential equations becomes particularly important for multiphysics and multiscale applications. In recent years, the efficient implementation of these methods in numerical software packages, more specifically to be used in supercomputers, has drawn some attention. This volume contains all invited papers, as well as the contributed papers focusing on finite volume schemes for elliptic and parabolic problems. They include structure-preserving schemes, convergence proofs, and error estimates for problems governed by elliptic and parabolic partial differential equations. The second volume is focused on finite volume methods for hyperbolic and related problems, such as methods compatible with the low Mach number limit or able to exactly preserve steady solutions, the development and analysis of high order methods, or the discretization of kinetic equations.
