Academic Career and Research Areas
The research interests of Professor Kaltenbach (b. 1961) cover methods for active and passive flow control that are geared towards improving the properties of technical systems in transportation, energy conversion and process technology with respect to safety, efficiency and their impact on the environment. High-resolution numerical approaches such as DNS and LES and wind tunnel experiments are used for flow analysis, identification of aeroacoustic noise sources and the prediction of sound.
Professor Kaltenbach studied at the University of Karlsruhe and TUM where he obtained a first degree in process engineering. After receiving a doctoral degree in 1992 with a thesis on atmospheric physics he spent three years as a research fellow at the Center for Turbulence Research of Stanford University. Until 2004 he worked as a research assistant at TU Berlin as a member of a research team focusing on flow control. Before joining TUM in 2011 he held positions in the R&D departments of companies operating in the transportation and process engineering industries.
