For the experiment, eight unevenly distributed ultrasonic distance sensors measure the local height of the wave surface. The resonance curves show maxima only for odd multiples of the fundamental resonance frequency . We explained this behavior using a simple intuitive "ping-pong" like model. Collision of wave fronts can be observed for higher frequencies. Also, the wave reflection on the walls can be treated as wave collision with itself. The non-linearity seems to be weak in our study so the delay in the wave propagation before and after the collision is small. Time-space plots show localized propagating waves with high amplitudes for frequencies near resonance. Between the peaks low amplitude and harmonic patterns are observed. However, for higher frequencies, the frequency band for localized waves becomes wider. In the Fourier space-time plane, this can be observed as a point for the harmonic patterns or a superposition of two lines: one line parallel to wave-vector k axis corresponding to the excitation frequency and a second line with inclination given by wave propagation velocity . For planned future work, this result will help us to reconstruct the whole water surface elevation using time-series from only a few measurement points}, language = {en} } @inproceedings{HarlanderSeeligGellertetal., author = {Harlander, Uwe and Seelig, Torsten and Gellert, Marcus and Viazzo, Stephane and Randriamampianina, Anthony and Egbers, Christoph and R{\"u}diger, G{\"u}nther}, title = {Stratorotational instability: nonlinear aspects at higher reynolds numbers}, series = {EUROMECH Colloquium 567, Turbulent mixing in stratified flows 22-25 March 2015, DAMTP, Centre for Mathematical Sciences, Cambridge}, booktitle = {EUROMECH Colloquium 567, Turbulent mixing in stratified flows 22-25 March 2015, DAMTP, Centre for Mathematical Sciences, Cambridge}, pages = {1}, language = {en} } @inproceedings{HasanuzzamanMerboldEgbers, author = {Hasanuzzaman, Gazi and Merbold, Sebastian and Egbers, Christoph}, title = {Experimentelle Untersuchung von Geb{\"a}ude-integrierten Windf{\"u}hrungen mit Laser-Doppler- Anemometrie}, series = {Lasermethoden in der Str{\"o}mungsmesstechnik, 23.

Str{\"o}mungsmechanische Simulationen (CFD) k{\"o}nnen dabei ein erstes Abbild zur Analyse von Kopplungseffekten zwischen den W{\"a}rmequellen und der Umgebung liefern. Diese sind jedoch oft zeitaufwendig und es bedarf zumindest ein gewisses Grundverst{\"a}ndnis, um die Fluid-mechanischen Parameter, das Vernetzen der Geometrien und die gewonnenen Ergebnisse korrekt zu interpretieren. Erste analytische Ans{\"a}tze zur reduzierten Beschreibung von ungeh{\"a}usten Chips auf Leiterplattensubstrat k{\"o}nnen durch thermische Widerstandsnetzwerke abgebildet und durch Aufteilung der W{\"a}rmestr{\"o}me in Richtung Substrat (W{\"a}rmeleitung) und in Richtung des bewegten Fluides (Konvektion) n{\"a}her beschrieben werden.}, language = {de} } @phdthesis{Neben, author = {Neben, Matthias}, title = {3D-CFD der Gas-Partikel-Str{\"o}mung in einer Laval-D{\"u}se zur Vorhersage mechanischer Erosion}, address = {Cottbus}, pages = {138}, language = {de} } @article{TravnikovEgbers, author = {Travnikov, Vadim and Egbers, Christoph}, title = {Zur Stabili{\"a}t thermischer Konvektion im Kugelspalt unter Erdbedingungen Energietheorie}, language = {de} } @phdthesis{Hallol, author = {Hallol, Zeinab}, title = {Behaviour of energetic coherent structures in turbulent pipe flow at high Reynolds numbers}, publisher = {Cuvillier Verlag}, address = {G{\"o}ttingen}, isbn = {978-3-7369-7501-9}, pages = {146}, language = {en} } @inproceedings{BorciaBorciaBestehornetal., author = {Borcia, Ion-Dan and Borcia, Rodica and Bestehorn, Michael and Borcia, C. and Dumitrascu, N. and Egbers, Christoph}, title = {Drops on cylindrical surfaces}, series = {7th Conference of the International Marangoni Association, Vienna (Austria), June 23-26, 2014}, booktitle = {7th Conference of the International Marangoni Association, Vienna (Austria), June 23-26, 2014}, publisher = {Techn.
