Here we review the way to build analogue space–times in open channel flows by looking at the flow phase diagram and the corresponding analogue experiments performed during the last years in the associated flow regimes. Thin films like the circular jump with different dispersive properties are discussed with the introduction of a brand new system for the next generation of analogue gravity experiments: flowing soap films with their capillary/elastic waves. This article is part of a discussion meeting issue ‘The next generation of analogue gravity experiments’.

模拟时空的经典流体动力学：明渠流和薄膜

在这里，我们通过查看流动相图和过去几年在相关流态中进行的相应模拟实验，回顾了在明渠流动中建立模拟时空的方法。讨论了具有不同色散特性的圆形跳跃等薄膜，并引入了用于下一代模拟重力实验的全新系统：具有毛细管/弹性波的流动肥皂膜。本文是“下一代模拟重力实验”讨论会议问题的一部分。
