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. For further information please get in touch with: Dr Peter Jansohn, Phone +41 (0)56 310 28 71, [log in to unmask] Applications should be submitted to: Paul Scherrer Institut, Human Resources, 5232 Villigen PSI, Switzerland Miriam Zehnder, [log in to unmask] Ref. code 5303-01. 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.
