Meridional symmetry is broken by replacing the inner cylinder with a truncated cone (frustum). Waves are excited by individual longitudinal libration of the walls. The geometry is non-separable and exhibits wave focusing and wave attractors. We investigated laboratory and numerical results for the Ekman number E ≈ 10-6. inclination α = 5.71◦ and libration amplitudes ε 0.2 within the inertial wave band 0 < ω < 2Ω0 . Under the assumption that the inertial waves do not essentially affect the boundary-layer structure, we use classical boundary-layer analysis to study oscillating Ekman layers over a librating wall that is at an angle α = 0 to the axis of rotation. The Ekman layer erupts at frequency ω = f∗, where f∗ ≡ 2Ω0 sin α is the effective Coriolis parameter in a plane tangential to the wall. For the selected inclination this eruption occurs for the forcing frequency ω/Ω0 = 0.2. For the librating lids eruption occurs at ω/Ω0 = 2. The study reveals that the frequency dependence of the total kinetic energy Kω of the excited wave field is strongly connected to the square of the Ekman pumping velocity wE (ω) that, in the linear limit, becomes singular when the boundary layer erupts. This explains the frequency dependence of non-resonantly excited waves. By the localization of the forcing, the two configurations investigated, (i) frustum libration and (ii) lids together with outer cylinder in libration, can be clearly distinguished by their response spectra. Good agreement was found for the spatial structure of low-order wave attractors and periodic orbits (both characterized by a small number of reflections) in the frequency windows predicted by geometric ray tracing. For 'resonant' frequencies a significantly increased total bulk energy was found, while the energy in the boundary layer remained nearly constant. Inertial wave energy enters the bulk flow via corner beams, which are parallel to the characteristics of the underlying Poincar{\´e} problem. Numerical simulations revealed a mismatch between the wall-parallel mass fluxes near the corners. This leads to boundary-layer eruption and the generation of inertial waves in the corners.}, language = {en} } @inproceedings{KleinGhasemiHarlanderetal., author = {Klein, Marten and Ghasemi, Abouzar and Harlander, Uwe and Will, Andreas}, title = {Inertial wave excitation and wave attractors in a librating annulus: DNS}, series = {European Geosciences Union, General Assembly 2014, Vienna, Austria, 27 April -

Der Fokus liegt auf der verbesserten Aufl{\"o}sung der Schmierfilmdickenmessung und der Ringstoßlagen. Mit der erweiterten Kapillar- und Lichtleiterkonfiguration werden neue {\"O}ltransportvorg{\"a}nge entlang des Kolbenringpakets mittels Tracerinjektion und simultaner LiF-Messung beobachtet. Das methodische Vorgehen bei der optischen Analyse des Kapillarf{\"u}llungsgrades wird an einem Labor-Druckpr{\"u}fstand weiterentwickelt. Des Weiteren werden komplexe Simulationsmodelle erstellt, mit denen die Kolbensekund{\"a}r-bewegung, die Kolbenringbewegung, die Gasstr{\"o}mung im Ringpaket und der {\"O}ltransport im Ringpaket gekl{\"a}rt werden k{\"o}nnen. Die Kolbensekund{\"a}rbewegungsrechnung basiert auf einer FEM-Diskretisierung die aus CAD-Modellen s{\"a}mtlicher Bauteile abgeleitet ist. Die dreidimensionale Berechnung der Kolbenringbewegung erfolgt unter Ber{\"u}cksichtigung dynamisch wirkender Kr{\"a}fte aus der Bewegung, der Ringreibung, dem Gasdruck und den Zwischenring- dr{\"u}cken. Die Elastizit{\"a}t der Ringe wird ber{\"u}cksichtigt, so dass Biegung, Torsion und damit auch das Twisten abgebildet werden k{\"o}nnen. Nut- und Ringgeometrie sowie thermisch bedingte Verz{\"u}ge fließen ebenfalls in die Berechnung mit ein.
