Inertial wave attractors in librating cuboids

K Wu, BD Welfert, JM Lopez - Journal of Fluid Mechanics, 2023 - cambridge.org
Perturbed rapidly rotating flows are dominated by inertial oscillations, with restricted group
velocity directions, due to the restorative nature of the Coriolis force. In containers with some …

Comparison of Libration-and Precession-Driven Flows: From Linear Responses to Broadband Dynamics

K Wu, BD Welfert, JM Lopez - Fluids, 2024 - mdpi.com
Libration and precession are different body forces that are ubiquitous in many rapidly
rotating systems, particularly in geophysical and astrophysical flows. Libration is a …

BD Welfert, JM Lopez, K Wu - Proceedings of the …, 2023 - royalsocietypublishing.org
Flows in rapidly rotating fluid-filled containers are strongly constrained by the restorative
Coriolis force. Their responses to small amplitude perturbations may result in the excitation …

Reflections and focusing of inertial waves in a librating cube with the rotation axis oblique to its faces

K Wu, BD Welfert, JM Lopez - journal of fluid mechanics, 2020 - cambridge.org
The response to librational forcing of a cube in rapid rotation about a diagonal axis is
explored. In this orientation, the faces of the cube are all oblique to the rotation axis. The …
