Aerothermodynamische Untersuchung einer Wiedereintrittskonfiguration und ihrer Komponenten in einem impulsbetriebenen Hochenthalpie-Stoßkanal
(2008-05-30)During re-entry into the atmosphere of the earth at altitudes between 60 km to 80 km above ground, the kinetic energy of a re-entry vehicle is converted mostly into thermal energy of the ... -
Boundary layers and wind in turbulent thermal convection
(2014-07-24)This cumulative thesis is based on seven publications and is devoted to the investigation of turbulent thermal convection by means of Direct Numerical Simulations (DNSs). Special focus is placed on the boundary layers and ... -
Development of a time-resolved quantitative surface-temperature measurement technique and its application in short-duration wind tunnel testing
(2018-07-13)In this cumulative thesis, a time-resolved quantitative temperature-sensitive paint (TSP) measurement technique was developed and used to measure temperatures at subsonic and up to hypersonic flow velocities in two different ... -
Dynamik und Bifurkationsverhalten eines getriebenen Oszillators mit frei aufliegender Dämpfermasse
(2011-06-22)A driven spring-mass system supplemented by a loosely mounted, freely sliding damper mass is investigated. This oscillator is a simple model of a damping principle applied to turbine blades ... -
Experimental Acquisition and Characterisation of Large-Scale Flow Structures in Turbulent Mixed Convection
(2014-07-28)In this cumulative thesis, the superposition of shear flow and thermal convection, namely mixed convection, is investigated experimentally. The experiments were performed in a cuboidal sample with aspect ratios Gamma_xz = ... -
Experimental investigation of coherent structures generated by active and passive separation control in turbulent backward-facing step flow
(2015-08-06)This dissertation presents the experimental investigation of coherent structures which were generated by active and passive separation control devices in a turbulent backward-facing step (BFS) flow. The Reynolds number was ... -
Experimentelle Erfassung und Charakterisierung der dreidimensionalen großskaligen Strömungsstrukturen und -temperaturen in Rayleigh-Bénard-Konvektion
(2017-10-26)In this work the flow structures in Rayleigh-Benard-Convection (RBC) are experimentally studied. For this purpose, two cuboidal convection samples are designed and installed. Using water as working fluid, these two experiments ... -
Spatial Scaling of Large-Scale Circulations and Heat Transport in Turbulent Mixed Convection
(2013-02-18)The present study reports an experimental investigation of the scaling of large-scale coherent structures, their dynamics and heat transport in turbulent mixed convection. Based on a concept of spatial scaling, mixed ... -
Stoßinduzierte Strömungsablösung in transitionellen Grenzschichten
(2022-01-21)The effects of transitional shock-wave/boundary-layer interactions (SWBLI) on the induced heat loads and the development of the laminar-turbulent transition are the subject of this work. Experimental investigations were ...
