Simultaneous use of different measurement techniques
(determining the interaction between flow and flame)



 Instantaneous mapping of the interaction between a vortex of the flow field and the reaction zone in a CH<sub>4</sub>/air swirl flame. The flow field is represented by the arrows and streamlines, the reaction zone (red structure) was determined from the gradients of the OH distribution.
zum Bild Instantaneous mapping of the interaction between a vortex of the flow field and the reaction zone in a CH4/air swirl flame. The flow field is represented by the arrows and streamlines, the reaction zone (red structure) was determined from the gradients of the OH distribution.

Simultaneously applying several different measurement technologies produces correlated measurement data that mutually complement each other and which can reveal the causes of specific combustion phenomena. For example, simultaneous 2D LIF and PIV measurements can be used to visualise the interaction between the eddies of a turbulent flow field and the reaction zones of the flame. In this way, it is possible to describe the factors causing flame stabilisation or the processes involved in flame extinguishing. Other applications include simultaneous 2D OH and temperature measurements, or combined Raman/LIF measurements.
