  • Stochastic Spray and Chemically Reacting Flow in LS-DYNA®
    9th European LS-DYNA Conference 2013 _________________________________________________________________________________ Stochastic Spray and Chemically Reacting Flow In LS-DYNA® Kyoung-Su Im, Zen-Chan Zhang, and Grant O. Cook, Jr. Livermore Software Technology Corp. Livermore, CA 94551 1 Introduction The injection of fuel sprays into an automotive engine and liquid jets into a high-speed flow stream is an important process in modern automotive gasoline and diesel engines, and propulsion in gas turbine and supersonic vehicles. In such applications, the combustion performance depends strongly on spray atomization, penetration, and the mixing process between the free stream air and the liquid fuel. As a result, the study of liquid spray in such areas has become an important research topic. The spray can be represented by a stochastic equation giving the rate of change of the distribution function, f = , which at a given time changes the positions, x, velocities, v, Ý equilibrium radius, r, temperature, f x,v,r,T,y,y ,T,t distortion from sphericity, y, and the time rate of change dy/dt[1,2]. This equation is then coupled with ensemble averaged gas phase equations of mass, momentum, and energy conservation. In addition, for many engineering sprays, drop breakup and collisions must be considered when the drop Webber number is larger than a critical value. Thus the essential dynamics of spray and its interaction with a gas is an extremely complicated physical phenomenon. Much attention has recently been devoted to the chemically reactive simulation models in the fields of subsonic, supersonic, and hypersonic combustion. However, the modeling of chemically reacting flow is a challenging task because of the simultaneous contribution of a wide range of time scales to the system dynamics.

  • Notes on the Kiva-Ii Software and Chemically Reactive Fluid Mechanics
    NOTES ON THE KIVA-II SOFTWARE AND CHEMICALLY REACTIVE FLUID MECHANICS MICHAEL J. HOLST Numerical Mathematics Group Computing & Mathematics Research Division Lawrence Livermore National Laboratory Livermore, California NOTES ON THE KIVA-II SOFTWARE AND CHEMICALLY REACTIVE FLUID MECHANICS∗ Michael J. Holst Numerical Mathematics Group Computing & Mathematics Research Division Lawrence Livermore National Laboratory August 1, 1992 Abstract This report represents a set of working notes regarding the mechanics of chemically reactive fluids with sprays, and their numerical simulation with the KIVA-II software. KIVA-II is a large FORTRAN program developed at Los Alamos National Laboratory for internal combustion engine simulation. It is our hope is that these notes summarize some of the necessary background material in fluid mechanics and combustion, explain the numerical methods currently used in KIVA-II and similar combustion codes, and provide an outline of the overall structure of KIVA-II as a representative combustion program, in order to aid the researcher in the task of implementing KIVA-II or a similar combustion code on a massively parallel computer. The notes are organized into three parts as follows. In Part I, we give a brief intro- duction to continuum mechanics, to fluid mechanics, and to the mechanics of chemically reactive fluids with sprays. In Part II, we take a close look at the governing equations of KIVA-II, and discuss the methods employed in the numerical solution of these equations. We draw some conclusions and make some observations in Part III. ∗These notes were written while the author was visiting Lawrence Livermore National Laboratory during the summer of 1992, on loan from the Numerical Computing Group in the Department of Computer Science at the University of Illinois, Urbana-Champaign.

    NASA Numerical and Experimental Evaluation of UTRC Low Emissions Injector Yolanda R. Hicks,1 Sarah A. Tedder,2 Robert C. Anderson,3 and Anthony C. Iannetti4 NASA Glenn Research Center, Cleveland, Ohio, 44135, USA Lance L. Smith5 and Zhongtao Dai6 United Technologies Research Center, East Hartford, CT, 06108, USA Computational and experimental analyses of a PICS—Pilot-In-Can-Swirler technology injector, developed by United Technologies Research Center (UTRC) are presented. NASA has defined technology targets for near term (called “N+1”, circa 2015), midterm (“N+2”, circa 2020) and far term (“N+3”, circa 2030) that specify realistic emissions and fuel efficiency goals for commercial aircraft. This injector has potential for application in an engine to meet the Pratt & Whitney N+3 supersonic cycle goals, or the subsonic N+2 engine cycle goals. Experimental methods were employed to investigate supersonic cruise points as well as select points of the subsonic cycle engine; cruise, approach, and idle with a slightly elevated inlet pressure. Experiments at NASA employed gas analysis and a suite of laser-based measurement techniques to characterize the combustor flow downstream from the PICS dump plane. Optical diagnostics employed for this work included Planar Laser-Induced Fluorescence of fuel for injector spray pattern and Spontaneous Raman Spectroscopy for relative species concentration of fuel and CO2. The work reported here used unheated (liquid) Jet-A fuel for all fuel circuits and cycle conditions. The initial tests performed by UTRC used vaporized Jet-A to simulate the expected supersonic cruise condition, which anticipated using fuel as a heat sink. Using the National Combustion Code a PICS-based combustor was modeled with liquid fuel at the supersonic cruise condition.
