Technische Universität Berlin is seeking a research associate for PhD-level research in the Chair of Numerical Fluid Dynamics within the Faculty of Mechanical Engineering and Transport Systems, Institute of Fluid Mechanics and Technical Acoustics. The project focuses on developing and implementing laser absorption spectroscopy diagnostics for rotating detonation combustors. The researcher will investigate optical access concepts and integrate laser-optical systems into rotating detonation combustion facilities, enabling quantitative measurements of H 2 O concentration and gas temperature in highly transient reacting flows. The work combines experimental fluid mechanics, combustion diagnostics, optical measurement techniques, and scientific data analysis. Responsibilities include designing, executing, and evaluating experimental campaigns across operating conditions; developing data acquisition, signal-processing, and post-processing tools; assessing measurement uncertainties and diagnostic performance; and generating reference datasets that characterize combustor operating conditions and combustion processes. The researcher will collaborate closely with international project partners at KAUST on advanced multi-parameter diagnostic techniques for rotating detonation combustor applications. The role also supports future experimental campaigns through baseline measurements, diagnostic infrastructure, and characterization of operating conditions.
