Post-doc position in laser spectroscopy in combustion

13.09.2004

Post-doc positions are available in the Laboratory for High Temperature Gas Kinetics, University of Groningen.

Project: consequences of hydrogen addition for the combustion of natural gas

Description:

One possible scenario for the transition from the current use of fossil fuel to a future sustainable energy supply is by the addition of hydrogen to natural gas. However, the changes in combustion properties with hydrogen addition can result in the malfunction of combustion equipment. In the Laboratory for High Temperature Gas Kinetics at the University of Groningen, research is being performed to catagorize and understand these changes in combustion behavior.

Specifically, both the ignition behavior of natural gas/hydrogen mixtures under gas engine conditions will be studied using a rapid compression machine, "RCM" (currently being designed). In addition to measurement of the changes in ignition delay times, the goal of this work is to measure important intermediates in ignition using laser spectroscopic methods. A Ph.D. student is currently working on this. In addition, the changes in premixed and diffusion flame structure upon hydrogen addition, in particular changes in pollutant formation (NOx, soot) at atmospheric pressure, must be determined. To do so, we rely on various spectroscopic methods available in our laboratory: laser-induced fluorescence, cavity ringdown spectroscopy, coherent anti-Stokes Raman scattering, spontaneous Raman scattering and diode laser absorption spectroscopy. Further, the project includes the study of the ignition of hydrogen-natural gas mixtures under the dilute conditions resembling those in high temperature furnaces. For these measurements, a high temperature flow reactor will be built.

The postdoc is to supervise the work in the RCM (both ignition and spectroscopy) and to perform the flame structure studies; we also expect the postdoc to take an active part in the construction of the flow reactor.

The required qualifications for the postdoc are: a Ph.D. in chemical physics or related field, with expertise in small molecule spectroscopy. Knowledge of gas dynamics and/or combustion is a definite advantage, but candidates with strong spectroscopic backgrounds who are willing to master these subjects are encouraged to apply.

The position is available for a period of 2 years with possible 1 year extension. Although the actual salary is determined in a later stage in the application process, an indication of the initial salary is roughly EUR2500 per month.
