First-order cosmological phase transitions are an intriguing source of gravitational waves. Depending on the temperature of the phase transition, the gravitational wave spectrum can be observed by pulsar timing arrays, space-based interferometers or ground-based experiments. Quantifying the produced power spectrum is however quite challenging, and non-linear hydrodynamics and turbulence are essential for robust predictions. The aim of the presentation is to summarize the history of the field and also discuss some recent developments.
