Preface to Combustion science. A Theme issue published by The Royal Society.

All the papers in this issue are concerned with fundamental aspects of combustion theory. Combustion science finds many practical applications in developments leading, for example, to improvements in the efficiency and performance of combustion systems, reductions in emissions of noxious pollutants, and the minimization of explosion and fire hazards during the transport, storage and use of combustible substances. Many of these papers discuss topics in the general area of hazards due to explosions and fires. All of them describe time-dependent combustion processes. The 11 papers are grouped together under four headings: Initiation of Explosions, Deflagrations, Detonations, and Combustion of Solids.
