Students of chemical engineering with a passion for process engineering challenges and a preference for experimental work. Knowledge of optical diagnostics or aerosol measurement techniques may be helpful to get started, but is not mandatory.

Motivation:

In the unique research approach "Clean Circles - Iron as an energy carrier in a carbon-neutral circular economy", iron with its oxides is to be employed in a cycle as a carbon-free chemical energy carrier for the storage of renewably generated electricity. Renewably generated electricity is used to reduce iron oxide (storage). Locally and temporally separated from this, the iron is oxidized with the release of energy to generate electricity (storage out). Consequently, renewable energy is stored in large quantities, transported and made available on a CO2-free basis - a key challenge of the energy transition that has not yet been solved.

Aufgabenstellung:

At the Engler-Bunte-Institute, we investigate the oxidation of iron particle ensembles in complex flow fields. The aim of the proposed thesis is to experimentally determine the slip velocity between the solid iron particles and the gas phase during the reaction and under well-defined reference conditions. First, the iron particle burner/reactor must be modified to enable the measurement of the slip velocity. The intrusive and non-intrusive (optical) particle diagnostics developed at the institute are to be employed to determine the measurable target quantities.
