The predominant fraction of matter in the universe is in a fluid state, and the predominant fraction of that is turbulent. Turbulence mixes fluids efficiently, bringing reactants together that can ignite and burn. On a cosmic scale, such reactions can be chemical or nuclear. Chemical combustion in turbulent flow, also known as turbulent combustion, combines the disciplines of chemistry and flow physics and must also deal with the effects on each other: the unsteady and chaotic dynamics of turbulent flow, the complexity of chemical reactions, the effects of the heat released by combustion on the turbulence, and, in turn, the effects of the turbulent environment on combustion itself. Any analysis of turbulent-combustion phenomena must deal with the flow and chemical reactions as coupled processes.
