A3: Experimental Investigation of Particle Loaded Flow in a Pulsation Reactor

For the industrial production of innovative materials needed for the transformation of our transportation system, the operational management of pulsation reactors has to be optimized with the goal of energy efficient production, especially with regard to the material properties. Temperature, pressure, flow velocity, particle size and velocity, as well as pulsation frequency were identified as process-influencing parameters, whereby the underlying physical relationships between these and the material properties are still largely unclear. For the optimization of the manufacturing process, appropriate models have to be developed, which must be validated and calibrated through measurements. This requires spatially resolved and, if necessary, time or phase-resolved measurements of the variables mentioned. The process parameters are then correlated with the resulting properties. Due to the complex boundary conditions, such as the high reactor temperature and the significant operating distance therefore required, as well as the prescribed spatial resolution in the μm range compared with the large reactor size of over 55 mm, very specific requirements are made of the suitable measuring systems. Furthermore, the measurements should be carried out non-invasively. Therefore, novel non-invasive optical measurement systems must be qualified, constructed, characterized, and used for the first time.
