This book was released on 2022. A Quasi-dimensional Charge Motion and Turbulence Model for Combustion and Emissions Prediction in Diesel Engines with a Fully Variable Valve Train available in PDF, EPUB and Kindle. Qirui Yang develops a model chain for the simulation of combustion and emissions of diesel engine with fully variable valve train (VVT) based on extensive 3D-CFD simulations, and experimental measurements on the engine test bench. The focus of the work is the development of a quasi-dimensional (QDM) flow model, which sets up a series of sub-models to describe phenomenologically the swirl, squish and axial charge motions as well as the shear-related turbulence production and dissipation. The QDM flow model is coupled with a QDM combustion model and a nitrogen oxides (NOx) / soot emission model. With the established model chain, VVT operating strategies of diesel engine can be developed and optimized as part of the simulation for specific engine performance parameters and the lowest NOx and soot emissions. Contents Fundamentals and state of the art Quasi-dimensional charge motion and turbulence model Coupling with a combustion model and an emission model Target Groups Researchers and students of mechanical engineering, especially automotive powertrains Research and development engineers in the fields of virtual engine development The Author Qirui Yang did his PhD project in the field of 0D/1D simulation of automotive powertrain at the Institute of Automotive Engineering (IFS) at University of Stuttgart. He works as a research engineer for simulation, project management and software development at the Research Institute FKFS in the field of Simulation and Artificial Intelligence of the Automotive Powertrain department.
Modelling Diesel Combustion

Download and read online ebook Modelling Diesel Combustion write by P. A. Lakshminarayanan. This book was released on 2022-01-21. Modelling Diesel Combustion available in PDF, EPUB and Kindle. This book comprehensively discusses diesel combustion phenomena like ignition delay, fuel-air mixing, rate of heat release, and emissions of smoke, particulate and nitric oxide. It enables quantitative evaluation of these important phenomena and parameters. Most importantly, it attempts to model them with constants that are independent of engine types and hence they could be applied by the engineers and researchers for a general engine. This book emphasizes the importance of the spray at the wall in precisely describing the heat release and emissions for most of the engines on and off-road. It gives models for heat release and emissions. Every model is thoroughly validated by detailed experiments using a broad range of engines. The book describes an elegant quasi-one-dimensional model for heat release in diesel engines with single as well as multiple injections. The book describes how the two aspects, namely, fuel injection rate and the diameter of the combustion bowl in the piston, have enabled meeting advanced emission, noise, and performance standards. The book also discusses the topics of computational fluid dynamics encompassing RANS and LES models of turbulence. Given the contents, this book will be useful for students, researchers and professionals working in the area of vehicle engineering and engine technology. This book will also be a good professional book for practising engineers in the field of combustion engines and automotive engineering.

Download and read online ebook A Quasi-Dimensional SI Burn Rate Model for Carbon-Neutral Fuels write by Sebastian Hann. This book was released on 2021-02-09. A Quasi-Dimensional SI Burn Rate Model for Carbon-Neutral Fuels available in PDF, EPUB and Kindle. Sebastian Hann describes the development of a quasi-dimensional burn rate model that enables the prediction of a fuel variation, without the need for a recalibration of the model. The model is valid for spark-ignition combustion engines powered by conventional and carbon-neutral fuels. Its high predictive ability was achieved by modeling the fuel-dependent laminar flame speed based on reaction kinetics calculations. In addition, the author discards a fuel influence on flame wrinkling by performing an engine measurement data analysis. He investigates the fuel influence on engine knock and models it via ignition delay times obtained from reaction kinetics calculations.
