Evaluating characteristics of turbulent flames by using IR thermography and PIV

The paper describes experimental results of determining scales of turbulent eddies in diffusion flames. The results are obtained by analyzing a set of 2D cross-sections cut from 3D semi-transparent flames. The comparison of data obtained by using the particle image velocimetry (PIV) method and infrared (IR) thermography is presented to demonstrate similarity between hydro- and thermodynamic parameters.
