Abstracts:

In the present work we report on application of tomographic PIV to an axisymmetric isothermal jet and laminar premixed propane/air flame. The aim was to measure 3D velocity fields near the nozzle exit through the whole depth of the flows. Thus, the thickness of the illuminated volume was 40 mm (with 15 mm nozzle diameter). This paper provides the results for a set of four cameras. It is discussed that the optical distortions caused by the combustion could produce particles image shift up to one pixel, that is critical for accuracy of tomographic PIV. In addition, it is necessary to increase the number of cameras used to measure, to reduce the effects of non-physical reconstruction artifacts or ghost particles.
