Download or read book CFD Simulation of Liquid Rocket Engine Injectors. Part 2. Simulations of the RCM-2 Experiment written by Richard Farmer and published by . This book was released on 2001 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sub-critical combustion case, RCM-2, was simulated with both heterogeneous and homogeneous spray combustion models. The MASCOTTE test data should be better than any which have been previously used to tune the several parameters in these models. It is unreasonable to expect that spray flames, even of hydrogen and oxygen, can be accurately predicted without extensive model validation with test data representative of the conditions which exists in rocket engine combustion chambers. Even global data such as chamber pressure and thrust have not been obtained for single coaxial element combustor flows. The IWRCM data provide a good starting point, but no CFD model tuning has yet been attempted for such experiments. Direct comparisons of predictions to test data at this point will not establish which of several modeling techniques is best.

Available in PDF, EPUB and Kindle. Book excerpt: A common feature of multiphase flows is that a dispersed or discontinuous phase is being carried by a continuous phase, for example water drops in gas flow, solid particles in water flow, or gas bubbles in liquid flow. The overall behavior of the flow is shaped largely by the interaction between the discontinuous elements--drops, particles, bubbles
Book Synopsis Swirl Coaxial Injector Development, Part II: CFD Modeling by :
Download or read book Swirl Coaxial Injector Development, Part II: CFD Modeling written by and published by . This book was released on 2002 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Injector design is critical to obtaining the dual goals of long engine life as well as providing high energy release efficiency in the main combustion chamber. Introducing a swirl component in the injector flow can enhance the propellant mixing and thus improve engine performance. A combined experimental and computational effort is underway to examine the properties of GOX-centered, swirl coaxial injectors to examine their performance and lifetime characteristics. These injectors can be easily manufactured and can be designed to maintain a low face temperature, which will improve engine life. Therefore, swirl coaxial injectors, which swirl liquid fuel around a gaseous oxygen core, show promise for the next generation of high performance staged combustion rocket engines utilizing hydrocarbon fuels. The purpose of this work is to not only examine the properties of these injectors, but also to develop a design methodology, utilizing a combination of high-pressure cold-flow testing, uni-element hot- fire testing, and computations to create a high performing, long life swirl coaxial injector for multi-element combustor use.

Book Synopsis Analysis of Injection Processes in an Innovative 3D-CFD Tool for the Simulation of Internal Combustion Engines by : Marlene Wentsch
Download or read book Analysis of Injection Processes in an Innovative 3D-CFD Tool for the Simulation of Internal Combustion Engines written by Marlene Wentsch and published by Springer. This book was released on 2018-05-16 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the large number of influencing parameters and interactions, the fuel injection and therewith fuel propagation and distribution are among the most complex processes in an internal combustion engine. For this reason, injection is usually the subject to highly detailed numerical modeling, which leads to unacceptably high computing times in the 3D-CFD simulation of a full engine domain. Marlene Wentsch presents a critical analysis, optimization and extension of injection modeling in an innovative, fast response 3D-CFD tool that is exclusively dedicated to the virtual development of internal combustion engines. About the Author Marlene Wentsch works as research associate in the field of 3D-CFD simulations of injection processes at the Institute of Internal Combustion Engines and Automotive Engineering (IVK), University of Stuttgart, Germany.

Book Synopsis Development of GOX/Hydrocarbon Multi-Element Swirl Coaxial Injector Technology by :
Download or read book Development of GOX/Hydrocarbon Multi-Element Swirl Coaxial Injector Technology written by and published by . This book was released on 2002 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In developing the advanced liquid rocket engine, injector design is critical to obtaining the dual goals of long engine life as well as providing high-energy release efficiency in the main combustion chamber. Introducing a swirl component in the injector flow can enhance the propellant mixing and thus improve engine performance. Therefore, swirl coaxial injectors, which swirl liquid fuel around a gaseous oxygen core, show promise for the next generation of high performance staged combustion rocket engines utilizing hydrocarbon fuels. Understanding the mixing and combustion characteristics of the swirl coaxial flow provides the insight of optimizing the injector design. A joint effort of Sierra Engineering (Sierra) and the Propulsion Directorate of the Air Force Research Lab (AFRL) was conducted to develop a design methodology, utilizing both high-pressure cold-flow testing and uni-element hot-fire testing, to create a high performing, long life swirl coaxial injector for multi-element combustor use. Several swirl coax injector configurations designed and fabricated by Sierra have been tested at AFRL. The cold-flow tests and numerical simulations have been conducted. The cold flow result provided valuable information of flow characteristics of swirl coaxial injectors. However, there are two important flow features of liquid rocket engines missed from the cold flow test: (1) the effect of combustion on the propellant mixing, and (2) the interaction of multiple injectors. The present work studies the hot flow environment specifically the multiple element swirl coaxial injector. Numerical simulations were performed with a pressure-based computational fluid dynamics (CFD) code, FDNS. CFD results produced loading environments for an ANSYS finite element thermal/structural model. Since the fuels are injected at temperature below its critical temperature, the effect of phase change and chemical reactions needs to be accounted for in the CFD model.
Book Synopsis CFD-based Surrogate Modeling of Liquid Rocket Engine Components Via Design Space Refinement and Sensitivity Assessment by : Yolanda Mack
Download or read book CFD-based Surrogate Modeling of Liquid Rocket Engine Components Via Design Space Refinement and Sensitivity Assessment written by Yolanda Mack and published by . This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Finally, a simplified computational model of multi-element injector flows was constructed to explore the sensitivity of wall heating and improve combustion efficiency to injector element spacing. Design space refinement using surrogate models and a multi-objective merit function formulation facilitated an efficient framework to investigate the multiple and competing objectives. The analysis suggests that by adjusting the multi-element injector spacing, the flow structures can be modified, resulting in a better balance between wall heat flux and combustion length.

Book Synopsis Turbulent Combustion by : Norbert Peters
Download or read book Turbulent Combustion written by Norbert Peters and published by Cambridge University Press. This book was released on 2000-08-15 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: The combustion of fossil fuels remains a key technology for the foreseeable future. It is therefore important that we understand the mechanisms of combustion and, in particular, the role of turbulence within this process. Combustion always takes place within a turbulent flow field for two reasons: turbulence increases the mixing process and enhances combustion, but at the same time combustion releases heat which generates flow instability through buoyancy, thus enhancing the transition to turbulence. The four chapters of this book present a thorough introduction to the field of turbulent combustion. After an overview of modeling approaches, the three remaining chapters consider the three distinct cases of premixed, non-premixed, and partially premixed combustion, respectively. This book will be of value to researchers and students of engineering and applied mathematics by demonstrating the current theories of turbulent combustion within a unified presentation of the field.
