Book Synopsis Simulation of Multiphase and Chemical Reactive Flows Based on Five Equation Model by : Yu-Hsuan Huang

Book excerpt: In the simulation of scramjet engines, many complex physical phenomena are involved, such as the fuel atomization, mass transition, and chemical reactions. In order to understand these complex physical phenomena, the purpose of the current thesis is to develop an in-house code for analyzing the flow structures of the scramjet engine. In this study, we first used the five-equation multiphase flow model and the Lagrangian method to reproduce the process of the fuel atomization and evaporation in a flow over side jet problem. Shock waves, recirculation zones and breakup processes of droplet particles were well captured. Comparing the results, we found that the five-equation multiphase model shows a better resolution in the shock capturing, comparing with the single phase Navier-Stokes equations. Then, we combined the five-equation multi-phase model and the single-step reaction model to simulate the formation of the cell structures in the detonation tube. The detonation waves under various operating conditions were discussed based on a single-step reaction model to model the complex reactions. Finally, a preliminary simulation of the DLR scramjet is performed. The current works have achieved satisfactory agreement compared to the experimental data no matter in reacting flow case or non-reacting flow case.

Book Synopsis Multiphase reacting flows: modelling and simulation by : Daniele L. Marchisio

Download or read book Multiphase reacting flows: modelling and simulation written by Daniele L. Marchisio. This book was released on 2007-10-16. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the most widely applicable modeling approaches. Chapters are organized in six groups covering from fundamentals to relevant applications. The book covers particle-based methods and also discusses Eulerian-Eulerian and Eulerian-Lagrangian techniques based on finite-volume schemes. Moreover, the possibility of modeling the poly-dispersity of the secondary phases in Eulerian-Eulerian schemes by solving the population balance equation is discussed.

Book Synopsis Chemical Reactor Modeling by : Hugo A. Jakobsen

Download or read book Chemical Reactor Modeling written by Hugo A. Jakobsen. This book was released on 2014-04-02. Available in PDF, EPUB and Kindle. Book excerpt: Chemical Reactor Modeling closes the gap between Chemical Reaction Engineering and Fluid Mechanics. The second edition consists of two volumes: Volume 1: Fundamentals. Volume 2: Chemical Engineering Applications In volume 1 most of the fundamental theory is presented. A few numerical model simulation application examples are given to elucidate the link between theory and applications. In volume 2 the chemical reactor equipment to be modeled are described. Several engineering models are introduced and discussed. A survey of the frequently used numerical methods, algorithms and schemes is provided. A few practical engineering applications of the modeling tools are presented and discussed. The working principles of several experimental techniques employed in order to get data for model validation are outlined. The monograph is based on lectures regularly taught in the fourth and fifth years graduate courses in transport phenomena and chemical reactor modeling and in a post graduate course in modern reactor modeling at the Norwegian University of Science and Technology, Department of Chemical Engineering, Trondheim, Norway. The objective of the book is to present the fundamentals of the single-fluid and multi-fluid models for the analysis of single and multiphase reactive flows in chemical reactors with a chemical reactor engineering rather than mathematical bias. Organized into 13 chapters, it combines theoretical aspects and practical applications and covers some of the recent research in several areas of chemical reactor engineering. This book contains a survey of the modern literature in the field of chemical reactor modeling.
