Flow and combustion in internal combustion engines are inherently three-dimensional and transient in time and space. Ideally, experimental efforts should therefore deliver instantaneous 3D snapshots to characterize structure, quantify species concentrations, temperature and velocities. This is important because averaging or sequential measurements will loose essential information about nonlinear couplings, such as flame-flow interaction. Experimental efforts are therefore underway to develop means for measuring the instantaneous and the time-dependent 3D-structure of flows, sprays and flames. Specifically, efforts based on single camera-based detectors are of interest in internal combustion research since optical access for multiple cameras can be an issue. Examples discussed include a single camera tomographic particle tracking velocimetry approach that enables high-speed 3D flow measurements and plenoptic imaging in translucent systems applied to quantify geometric details of fuel sprays, flow-spray interaction, laser-induced fluorescence in a free jet, and chemiluminescence from flames.

Professor Volker Sick teaches undergraduate laboratory courses in Mechanical Engineering. His research group develops and uses imaging techniques to investigate foundations that are essential to developing new engine concepts. His research covers fundamental physical and chemical aspects of laser spectroscopy and combustion and bridges all the way to applications in industry. As Associate Vice President, Professor Sick serves as liaison between the U-M Office of Research (UMOR) and scholarly and creative activities across the University in the natural sciences and engineering. As a senior member of the UMOR administrative team he helps orchestrate major interdisciplinary initiatives, deals with policy issues, and works with U-M's Washington, D.C. office to promote the university's research agenda. He also oversees several UMOR units, including the University of Michigan Energy Institute (UMEI), the University of Michigan Transportation Research Institute (UMTRI), the Mobility Transformation Center (MTC), and Women in Science and Engineering (WISE). A graduate of the University of Heidelberg in Germany with degrees in chemistry and physical chemistry, he came to U-M as an associate professor in the College of Engineering in 1997. Elected an SAE Fellow in 2008 for his contributions to automotive technology, he has been widely recognized for his leadership in research, teaching, and service.
