This paper reviews dynamics of turbulent premixed flames from the ignition process of combustible mixtures in different regimes to subsequent flame initiation, development and propagation to flame global quenching. A transition on minimum ignition energy in flamelet and distributed regimes is first presented. Different experimental methods used to measure turbulent burning velocities (ST) are then discussed, revealing the so-called bending effect. A general correlation of ST in terms of turbulent straining and the Damköhler number is proposed. Furthermore, the effect of radiation heat losses on ST is briefly discussed. Finally, global quenching of premixed flames with turbulent straining, equivalence ratio, and radiative heat loss effects are reported, showing criteria of flame quenching by turbulence.
