For a project funded by the Swiss National Science Foundation (SNF) we seek
to recruit a PhD student
Your tasks
In this PhD thesis NO-LIF measurements in various flames between
atmospheric pressure and 40 bars will be performed. The impact of pressure,
temperature and flame composition on signal intensity and detection
selectivity will be assessed as a function of excitation and detection
wavelengths and flame conditions. The measurement technique will be
optimized using a high-pressure, laminar flow burner with a highly stationary
flame. The goal of the proposed project is to put at our disposal the
experimental apparatus and the know-how to measure, analyze and interpret
NO LIF signals at high pressures and temperatures, i.e. conditions similar to
those encountered in gas turbines and Diesel engines. This includes the
development of a capability to predict the combined signals from NO and
interfering species, namely O2 and CO2.
Your profile
Suited candidates have a university degree in natural science (physics,
chemistry) or engineering (chemical engineering, mechanical engineering),
preferably with experience in optical measurement techniques and talent for
experimental work. You enjoy working in a collaborative, interdisciplinary and
international environment. Good communication skills in English are a plus.

The Paul Scherrer Institute is a centre for multi-disciplinary research and one
of the world’s leading user laboratories. With its 1300 employees it belongs as
an autonomous institution to the Swiss ETH domain and concentrates its
activities on solid-state research and materials sciences, elementary particle
physics, energy and environmental research as well as biology and medicine.
The group Combustion Technologies of the Combustion Research Laboratory
performs studies on low emission combustion techniques for gas turbine
applications and internal combustion engines. Special emphasis is given to the
use of non-intrusive optical measurement techniques (laser spectroscopy) for
the characterization of premixed and diffusion flames.
