Direct numerical simulation (DNS) is a valuable tool for the study of complex interactions between turbulence and combustion, thanks to its ability to resolve the wide range of time and length scales involved. Its application in the fundamental study of turbulent diffusion flames has been particularly fruitful in recent years, which led to some new findings, improved understanding of known phenomena and the development of new theories and models. This paper is concerned with the effects of heat release from finite‐rate chemistry on compressible turbulence. The present DNS results reveal intricate interactions among combustion, turbulent transport and mixing.
