Understanding fluid flows in planetary cores and subsurface oceans, as well as their signatures in available observational data (gravity, magnetism, rotation, etc.), is a tremendous interdisciplinary challenge. In particular, it requires understanding the fundamental fluid dynamics involving turbulence and rotation at typical scales well beyond our day-to-day experience. To do so, laboratory experiments are fully complementary to numerical simulations, especially in systematically exploring extreme flow regimes for long duration. In this review article, we present some illustrative examples where experimental approaches, complemented by theoretical and numerical studies, have been key for a better understanding of planetary interior flows driven by some type of mechanical forcing. We successively address the dynamics of flows driven by precession, by libration, by differential rotation, and by boundary topography.

了解行星核心和地下海洋中的流体流动，以及它们在可用观测数据（重力、磁力、自转等）中的特征，是一项巨大的跨学科挑战。特别是，它需要了解基本流体动力学，包括典型尺度上的湍流和旋转，远远超出我们的日常经验。为此，实验室实验与数值模拟完全互补，特别是在系统地探索长期极端流动状态方面。在这篇评论文章中，我们提供了一些说明性示例，其中实验方法，辅以理论和数值研究，对于更好地理解由某种类型的机械强迫驱动的行星内部流动至关重要。我们相继解决了由岁差驱动的流动动力学问题，
