Our focus is on developing and applying tomographic techniques to produce instantaneous three-dimensional (3D) information from experiments in energy- and process-technology research. Such information is paramount to deepen our understanding of various phenomena in real flows, which are almost always unsteady or turbulent. In turn, this allows us to improve different technologies such as combustion devices, to be made more efficient or environmentally friendly.
We combine different types of measurements with computed tomography (CT), including background-oriented schlieren (BOS) that is relevant in reactive and non-reactive flows, and radiative emission in combusting gases. Our generic multi-camera setup allows us to produce unprecedented reconstructions based on multi-simultaneous measurements. This enables us to investigate different effects within the same volume, and such information is rarely available experimentally.
The techniques that we develop can be suited for laboratory settings, which are ideal for fundamental studies, and for the more challenging industrial environments where accessibility is almost always limited. Our algorithms are tested through diverse applications and phantom studies. A phantom is an exactly known field that can be compared to its reconstruction, allowing for a quantitative assessment of the reconstruction. We use realistic phantoms, for example from flow simulations, that represent the complexity of the fields that are to be reconstructed.
