Low-speed (low Mach number) combustion is important in a variety of contexts, including furnaces, spark ignition engines, forest fires, and rocket motors. Fundamentally it is concerned with problems of ignition and with flames. This workshop will focus on two areas in which a large number of fundamental combustion topics are relevant, namely the burning of solid propellants, and of liquid fuel sprays.

Heterogeneous solid propellants support premixed flames and diffusion flames. The diffusion flames have edges in which hybrid combustion occurs. The interaction of these flames with the solid propellant, with local flows, and with acoustic waves is of importance in predicting steady burning rates, erosive burning, and instabilities. Fuel spray burning also is concerned with diffusion flames and premixed flames supported in an environment characterized by nonuniform flow and heterogeneity. Although these problems have been of interest for many decades, many aspects are not well understood. However, fresh mathematical, physical, and computational ideas are yielding new, important results, and this workshop will examine these and explore future directions. The emphasis will be on fundamental flame and flow issues.
