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} } @misc{KochHarlanderEgbers, author = {Koch, Sandy and Harlander, Uwe and Egbers, Christoph}, title = {Wave-attractors and mean flow in a spherical shell due to time-modulated rotation}, language = {en} } @inproceedings{OenguenerZanounFiorinietal., author = {{\"O}ng{\"u}ner, Emir and Zanoun, El-Sayed and Fiorini, Tommaso and Bellani, Gabriele and Shahirpour, Amir and Egbers, Christoph and Talamelli, Alessandro}, title = {Wavenumber Dependence of Very Large-Scale Motions in CICLoPE at 4800 ≤ Reτ ≤ 37.000}, series = {Progress in Turbulence VII, Proceedings of the iTi Conference in Turbulence 2016}, booktitle = {Progress in Turbulence VII, Proceedings of the iTi Conference in Turbulence 2016}, editor = {{\"O}rl{\"u}, Ramis and Talamelli, Alessandro and Peinke, Joachim and Oberlack, Martin}, publisher = {Springer}, address = {Cham}, isbn = {978-3-319-57933-7}, pages = {101 -- 106}, language = {en} } @inproceedings{KochHarlanderHollerbachetal., author = {Koch, Sandy and Harlander, Uwe and Hollerbach, Rainer and Rabitti, A. and Maas, L.
