In this talk I will discuss the possibilities to mimic black hole physics in fluid flows. The starting point is an analogy discovered by Unruh between the propagation of sound in a flowing fluid and waves around a black hole. In these analog setups, it is possible to test various black hole effects, challenge their robustness, and even observe them in a laboratory experiment. In a first part, I will present ongoing research on the Hawking effect and its analogues. In a second one I will discuss a recent experimental observation of superradiance in an analogue flow.
