The project concerns development of new optical emission/absorption tomography methods for combustion diagnostic to obtain 2D information about gas temperature and gas concentrations. It comprises a combined theoretical, numerical and experimental approach, with the possibility of participation in on-going projects. The aim is to develop tomographic methods for lab-scale as well as full-scale measurement in hot gas flows, e.g. diesel engine or exhaust, boilers and flames. The project will be based on in situ optically-based spectroscopic methods in infra-red (IR) and ultra-violet (UV) ranges to be developed at Risø DTU and, moreover, involves significant extensions and new developments in the field of optical tomography. In particular, the following problems will be addressed:
- Optical properties of gases in IR and UV spectral region at high gas temperature and effect of pressure.
- Development of software and algorithms for IR and UV optical emission tomography system and methodology for in situ spectra-resolved gas concentration and
- Experiments on laboratory hot gas flow and data processing using a new infrared (IR) emission/absorption multi-channel spectrometer for simultaneous measurements of gas temperature and gas composition.
The work will be performed in close contact with other member in the group, partners and industry. The results should ultimately contribute to the extension of the group’s capabilities for in situ optical diagnostic in various combustive environments.
We offer an interesting and challenging PhD project in an international atmosphere.
You are expected to have a university or master degree. It will be an advantage if you have a good mathematical background and knowledge in solution of inverse ill-posed problems. Moreover, it is beneficial that you have experience in one or more of the areas: optics, gas spectroscopy, combustion physics and good numerical skills.
