Paper Abstract

The paper presents experimental investigation results of turbulent vortices scales in diffusion flames. Comparison of obtained data on the basis of digital tracer visualization and thermography was carried out. A good correlation is obtained between the sizes of large vortex structures in the velocity field, recorded using the PIV method, and the size of temperature inhomogeneities, recorded by flame thermography.
