In technical combustion processes, the interaction of the flame with the turbulent flow field plays a crucial role in the stability, safety and efficiency of energy conversion. Turbulent combustion is a three-dimensional multiscale phenomenon. In the operation of technical burners, transient combustion states such as spark and self-ignition, flame extinction and flashback can also occur. To investigate these phenomena, imaging laser-optical measurement methods are developed in this work and simultaneously applied to the measurement of transient flames in a turbulent...
