摘要

超重力可以通过在离心装置中产生向心加速度施加的场来实现。在岩土工程问题中，这种装置常用于测试土的响应。在这里，我们提出了离心装置的潜在用途，以研究流体力学的各种主题。首先回顾了与流体力学相关的标度律，并描述了控制机体力的优势。在这种实验中，一个明显的缺点是离心机中存在不必要的科里奥利效应。然而，我们建议利用这种效应来研究特别是在赤道地区发生的地球物理流体动力学问题。

Geophysical fluid dynamics in the hypergravity field

Hypergravity can be realized by creating a field imposed by centripetal acceleration in a centrifuge apparatus. Such an apparatus is often used to test soil response in geotechnical engineering problems. Here we present the potential usage of a centrifuge apparatus to study various topics in hydrodynamics. The scaling law associated with hydrodynamics is first reviewed, and the advantage of controlling the body force is described. One of the perceived disadvantages in such experiments is the unwanted presence of the Coriolis effect in the centrifuge. However, we propose exploiting this effect to our advantage to study geophysical fluid-dynamic problems that occur particularly in the equatorial region.

期刊介绍： Acta Mechanica Sinica, sponsored by the Chinese Society of Theoretical and Applied Mechanics, promotes scientific exchanges and collaboration among Chinese scientists in China and abroad. It features high quality, original papers in all aspects of mechanics and mechanical sciences. Not only does the journal explore the classical subdivisions of theoretical and applied mechanics such as solid and fluid mechanics, it also explores recently emerging areas such as biomechanics and nanomechanics. In addition, the journal investigates analytical, computational, and experimental progresses in all areas of mechanics. Lastly, it encourages research in interdisciplinary subjects, serving as a bridge between mechanics and other branches of engineering and the sciences. In addition to research papers, Acta Mechanica Sinica publishes reviews, notes, experimental techniques, scientific events, and other special topics of interest.
