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 introduction 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.
