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 ... -
Experimental Investigation of Micrometric Droplets and Artificial Particles
(2022-04-28)Clouds and atmospheric particles (e.g. ice crystals, smoke, dust or pollen) heavily influence Earth's energy budget and contribute to the largest uncertainties in climate prediction models. Their treatment involves a huge ... -
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 ... -
Experimentelle Untersuchungen von Fingerströmung und thermohalinen Treppen für instabile Auftriebsverhältnisse
(2016-04-19)Finger convection is observed experimentally in an electrodeposition cell in which a destabilizing gradient of copper ions is maintained against a stabilizing temperature gradient. This double-diffusive system shows finger ... -
Konzeption einer Messsonde zur quantitativen zeitaufgelösten Detektion von CNG im Motor mittels IR-Strahlung
(2017-10-18)Rising greenhouse gas emissions caused by the transport sector are one factor that contributes to global warming. Consequently, the EU has decided on new regulations concerning the emissions of automobiles and on the ... -
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 ... -
Understanding the brightness variations of Sun-like stars on timescales of stellar rotation
(2021-01-21)Solar brightness varies on timescales from minutes to decades. In particular, the observed photometric variability can directly relate to the rotation period. Our understanding of this link allows extrapolations from the ...
