Classical hydrodynamics for analogue space–times: open channel flows and thin films

Abstract

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'.
