This book was released on 2018-05-16. Analysis of Injection Processes in an Innovative 3D-CFD Tool for the Simulation of Internal Combustion Engines available in PDF, EPUB and Kindle. 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.

This book was released on 2011-03-07. An Innovative 3D-CFD-Approach towards Virtual Development of Internal Combustion Engines available in PDF, EPUB and Kindle. In the engine development process, simulation and predictive programs have continuously gained in reliance. Due to the complexity of future internal combustion engines the application of simulation programs towards a reliable “virtual engine development” is a need that represents one of the greatest challenges. Marco Chiodi presents an innovative 3D-CFD-tool, exclusively dedicated and optimized for the simulation of internal combustion engines. Thanks to improved or newly developed 3D-CFD-models for the description of engine processes, this tool ensures an efficient and reliable calculation also by using coarse 3D-CFD-meshes. Based on this approach the CPU-time can be reduced up to a factor 100 in comparison to traditional 3D-CFD-simulations. In addition an integrated and automatic “evaluation tool” establishes a comprehensive analysis of the relevant engine parameters. Due to the capability of a reliable “virtual development” of full-engines, this fast response 3D-CFD-tool makes a major contribution to the engine development process. Südwestmetall-Förderpreis 2010

This book was released on 2020-12-15. Potential of Water Injection for Gasoline Engines by Means of a 3D-CFD Virtual Test Bench available in PDF, EPUB and Kindle. Water injection is one of the most promising technologies to improve the engine combustion efficiency, by mitigating knock occurrences and controlling exhaust gas temperature before turbine. As result, the engine can operate at stoichiometric conditions over the whole engine map, even during the more power-demanding RDE cycles. Antonino Vacca presents a methodology to study and optimize the effect of water injection for gasoline engines by investigating different engine layouts and injection strategies through the set-up of a 3D-CFD virtual test bench. He investigates indirect and direct water injection strategies to increase the engine knock limit and to reduce exhaust gas temperature for several operating points.

This book was released on 2020-09-14. Modeling of Real Fuels and Knock Occurrence for an Effective 3D-CFD Virtual Engine Development available in PDF, EPUB and Kindle. To drastically reduce the emission of greenhouse gases, the development of future internal combustion engines will be strictly linked to the development of CO2 neutral fuels (e.g. biofuels and e-fuels). This evolution implies an increase in development complexity, which needs the support of engine 3D-CFD simulations. Francesco Cupo presents approaches to accurately describe fuel characteristics and knock occurrence in SI engines, thus improving the current simulation capability in investigating alternative fuels and innovative combustion processes. The developed models are successfully used to investigate the influence of ethanol-based fuels and water injection strategies on knock occurrence and to conduct a virtual fuel design for and engine operating with the innovative SACI combustion strategy.

This book was released on 2019-11-29. Turbocharger Integration into Multidimensional Engine Simulations to Enable Transient Load Cases available in PDF, EPUB and Kindle. Despite the increasing interest in multidimensional combustion engine simulation from researchers and industry, the field of application has been restricted to stationary operating points for turbocharged engines. Andreas Kächele presents a 3D-CFD approach to extend the simulation into the transient regime, enabling the detailed analysis of phenomena during changes in engine operating point. The approach is validated by means of a virtual hot gas test bench and experiments on a two-cylinder engine.
