Use of the Combustion and Stochastic Water Spray Modules in the LS-DYNA Compressible Flow Solver

Recent development of the chemistry and stochastic water spray modules in the CESE LS-DYNA® compressible flow solver will be reported in this presentation. For the chemistry, detailed descriptions about CHEMKIN input files including the thermodynamics and transport data files will be presented. How to construct of the keyword files is also demonstrated for the various chemically reactive flows. Limitations of the current chemistry module and future development with reduced chemistry will be discussed. For the stochastic water spray, the concept of the stochastic particle, breakup models such as the TAB and KH&RT hybrid models, and collision models are described and corresponding keyword setups are explained with water spray flows. Limitation and current developments including fuel vaporization models will be also presented.
