High-speed camera system for researching thermofluid systems (renewal)

• Subject Area: Fluid Mechanics, Technical Thermodynamics and Thermal Energy Engineering
• Term: since 2026
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 584581002

The high-speed camera system will be used to record dynamic processes in chemically reactive flows. The focus is on investigating thermochemical, high-temperature energy conversion processes using optical and laser diagnostic measurement methods. The applicant is currently transferring these methods to other fields of research, such as electrochemical and catalytic systems. The high-speed cameras will measure turbulent flow fields of single- and two-phase flows, temperature fields of continuous gas and dispersed particle phases, wall temperatures, reaction zone topologies, and the geometric properties of dispersed particles. The following methods will be used for this purpose: particle image velocimetry (PIV), particle tracking velocimetry (PTV), pyrometry, laser-induced fluorescence (LIF), laser-induced phosphor thermometry, diffuse background illumination (DBI), and the Schlieren measurement method. The applicant has been developing and adapting some of these methods to new fields of application over the past two decades. They have contributed to a better understanding of thermochemical energy conversion processes, which is essential for the knowledge-based development of sustainable and clean energy conversion systems. The experimental measurement data collected by the applicant's working group significantly contributes to validating mathematical models for numerically simulating thermochemical energy conversion systems. To this end, various benchmark configurations have been set up that are in demand worldwide. To continue this work successfully, however, the four CMOS high-speed cameras must be replaced, as neither service nor sufficient spare parts are available for them. If one of the cameras fails, the tomographic and multiparameter measurements described above can no longer be performed.
