Short-Time Holography and Holographic PIV Applied to Engineering Problems

The present work reports on short-time holography as applied at the ‘Lehrstuhl A für Thermodynamik’of the ‘Technische Universität München’and possible applications of this measuring technique to the analysis of heat and mass transfer processes. The principal optical setup for the recording, reconstruction and evaluation of the holograms is explained through the example of a current research project. Short-time holography was applied to the analysis of the disintegration process of sprays and to two phase flow in an aerated stirred vessel. By using this measuring technique, new insights into two phase flow phenomena were obtained. The results led to a more detailed set of data which now serves as the basis for new approaches in modeling and numerically simulating two-phase-flow.
