Acceleration in an instationary rotating cylinder with a barrier

05/10/2023 - Lyke van Dalen

Experiments (PTV) have been performed on a rotating cylinder with a (partial) radial barrier. Inspired by the flow observed during accelerating and decelerating motion in the inner ear, different velocity patterns are tested to mimic head movements and study the effect of a change in velocity.

Within the vestibular system forces from angular accelerations, rather than from rotation itself, have previously been shown to influence information transfer of head motions. With recent experiments in our laboratory indicating inconsistencies with the current force estimation of impulsively started objects, we aim to shed more light on the influence of accelerations in rotational systems, and in particularly the vestibular system.
