Subject Area

Project identifier
Deutsche Forschungsgemeinschaft (DFG) - Project number 5471852
Experimental flow analysis occupies a significant and central role beside flow theory and numerics, applied in flow research as well as in broad fields of industrial practice. The purpose of an experiment is always to get a "picture" of the flow field to identify e.g. physical correlations or to verify applied flow models.
Comparisons with current increasingly-utilized numerical tools in research and practice (Computational Fluid Dynamics) reveal, that only very few experimental methods exist which can keep up with modern numerical methods according to their graphical expressiveness in spatio-visual analysis or the analysis of flow field dynamics. The research programme shall help to close this gap by moving the investigation of powerful imaging measurement methods for the analysis of complex spatial flow fields into the centre of the activities. The modern flow measurement technique shall be advanced with this program as an accepted key technology by cooperation with informatics and measurement physics of which applications extend the classical operational range of flow physics by far. These new experimental tools - together with numerics - can help to disclose the previously neglected world of instationary flow mechanics which will, in future, undoubtedly adopt a dominating position e.g. in the area of gas turbines, bio-fluidmechanics or flow control.
The research program is roughly divided in four application areas:
-- field measurement methods;
-- surface measurement methods;
-- flow measurement techniques based on micro electromechanical sensors (MEMS);
--measurement methods for complex transportation coefficients.
These four sub-areas will be edited by interdisciplinary research groups from the areas of flow mechanics (including users from applied engineering science), measurement physics and informatics (here methods for digital imaging and analysis). In the first step, the program will be supplemented by a basic experiment covering the resolution of time and space, accompanied by corresponding numerical simulations (presently Large-Eddy-Simulation). Further, a network shall be formed to attend the research initiative in a reasonable way i.a. with technology colloquiums (organised by the research partners) and transfer projects (organised by industry).
