Stimulated by the application of relativistic heavy ion collisions and new theoretical developments, such as the derivation of hydrodynamics from holography, the field of relativistic real fluids has seen unprecedented activity in later years. We now have a consistent framework where relativistic viscous hydrodynamics is regarded as a low-energy effective theory enforcing relevant conservation laws, as well as the Second Law of Thermodynamics. Moreover, the solutions to this effective theory act as an attractor to the evolution of the system regarding less coarse-grained descriptions. As a consequence of these breakthroughs, the field of real relativistic hydrodynamics is now ready to face new challenges, particularly in applications to the physics of the Early Universe and compact astrophysical objects. These new problems will test the theory in a regime where strongly nonlinear phenomena, very far from equilibrium, such as turbulence and shock waves, are very much the center of attention. They will also highlight the interaction of real fluids with gauge and gravitational fields. While pure formal arguments will help to gain a foothold in these new fields, at some point, large-scale numerical simulations will be necessary for steady progress. The aim of this Special Issue is to offer a platform for the leaders in the field in recent years, for newcomers, and for people whose main interest lies not in relativistic hydrodynamics, but in fields where relativistic hydro is likely to make major contributions, to exchange views on the present state of the art, the main challenges confronting us, and the new applications ready to be explored.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Entropy is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
