Fluid mechanical study of rotation-induced traumatic brain injury

This is the authors' abstract. We don't add key points for this paper.

Rotation-induced traumatic brain injury is a serious health concern. We present a novel experimental and theoretical approach to studying fluid-structure interactions between soft matter and its liquid surroundings under rapid rotational impact. Our theoretical model, developed using the Arbitrary Lagrangian-Eulerian method, has been verified and validated against experimental data. This work establishes a strong foundation for future research into rotation-induced brain concussions, where the transient fluid-structure interaction between the cerebrospinal fluid and the soft brain matter plays a critical role in impact transmission and mitigation.
