Multiphysics Modelling Of Fluid Particulate Systems

Multiphysics Modelling of Fluid-Particulate Systems provides an explanation of how to model fluid-particulate systems using Eulerian and Lagrangian methods. The computational cost and relative merits of the different methods are compared, with recommendations on where and how to apply them provided. The science underlying the fluid-particulate phenomena involves computational fluid dynamics (for liquids and gases), computational particle dynamics (solids), and mass and heat transfer. In order to simulate these systems, it is essential to model the interactions between phases and the fluids and particles themselves. This book details instructions for several numerical methods of dealing with this complex problem. This book is essential reading for researchers from all backgrounds interested in multiphase flows or fluid-solid modeling, as well as engineers working on related problems in chemical engineering, food science, process engineering, geophysics or metallurgical processing. Provides detailed coverage of Resolved and Unresolved Computational Fluid Dynamics - Discrete Element Method (CFD-DEM), Smoothed Particle Hydrodynamics, and their various attributes Gives an excellent summary of a range of simulation techniques and provides numerical examples Starts with a broad introduction to fluid-particulate systems to help readers from a range of disciplines grasp fundamental principles

The Predictive Science Academic Alliance Program (PSAAP) II at Stanford University investigated particle-laden turbulent flows in a radiation environment for concentrated solar power (CSP) applications. Over the course of the PSAAP project an extensive series of laboratory scale experiments and corresponding high fidelity simulations were designed and conducted for a conceptual volumetric solar energy receiver design. The configuration of interest involved the coupling of three distinct physical phenomena: fluid turbulence, particle dynamics, and the transport of thermal radiation.The work presented in this thesis is primarily focused on computational thermal radiation transport and multi-physics simulations of this conceptual solar energy receiver. The governing equations and numerical methods used to model the three major physical processes relevant to the PSAAP application (fluid, particles, and radiation) are presented. The couplings between the various processes are discussed due to their consequence on the data communication required by the computational solvers. The computational expense required to perform simulations of the PSAAP apparatus, due to the large range of length and time scales that needed to be resolved, required the use of high performance computing (HPC) systems. An overview of the multi-physics solver that was developed to simulate the physical processes relevant to the PSAAP application, Soleil-X, is given. Soleil-X used the Legion programming system, through the Regent programming language, in order to effectively use high performance computing systems with a variety of diverse architectures. A series of high fidelity radiative boundary conditions for the PSAAP multi-physics simulations were generated using specially developed emission models based on the radiation source used in the PSAAP experiments. The development, validation, and implementation of the custom emission models in the Monte Carlo Ray Tracing (MCRT) solver in Soleil-X are discussed. Then the full capability of Soleil-X is demonstrated with a multi-physics simulation of a particle laden open jet with co-flow that was radiatively heated with 10 [kW] of radiation.

"This volume is based on talks given at ASTRONUM-2007. This conference is the second in a series of international conferences organized by the Institute of Geophysics and Planetary Physics of the University of California at Riverside and the Laboratory for Research of the Fundamental Laws of the Universe of the French Commissariat of Atomic Energy. The conference subjects include turbulence and cosmic ray transport, astrophysical flows, space plasma flows, kinetic and hybrid simulations, numerical methods, algorithms, and frameworks, and data handling and visualization. All of these are of great importance for scientists investigating solar structure, the heliosphere, the Sun-Earth connection, and various astrophysical phenomena. The problems discussed at the conference involved significantly different scales, regions, or particle populations for which several sets of defining equations or concepts are necessary to understand the physical system in its entirety. This book will be of interest to specialists in applied mathematics, astrophysics, space physics, and computer science who apply novel numerical algorithms to the contemporary problems in these fields. Graduate students will find it a useful reference of the fundamental approaches to solving the fluid dynamics and Boltzmann equations governing space plasma flows." -- publisher's website
