Abstract: The cold flow of a prototype industrial burner in a cylindrical
combustion chamber is investigated. Two concentric annular axial jets simulate
this complex flow field, which is investigated using Laser Sheet flow
Visualization (LSV), Digital Particle Image Velocimetry (DPIV), Laser Doppler
Velocimetry (LDV) and Computational Fluid Dynamics (CFD). The aim is to advance
the physical understanding of combustion chamber flow fields and to assist the
development of CFD codes specialized in such flows. These simulations generate
large amount of data for various measured and calculated quantities. Thus,
visualization and comparison procedures are applied for the validation of
obtained results. The study reported here is one of the experiments applied in
the design of the Quantitative Flow Field Visualization (QFView) software, a
web-based environment which supports distributed data access. The application
of QFView data analysis greatly improved the understandings about the various
transition regions of the flow under investigation.
