Multicomponent relativistic dissipative fluid dynamics from the Boltzmann equation

We review the derivation of the fluid-dynamical equations of motion from kinetic theory. Applying this method we derive multicomponent relativistic second-order dissipative fluid dynamics from the Boltzmann equations for a reactive mixture of NS particle species with NQ intrinsic quantum numbers (e.g. electric charge, baryon number, and strangeness). The resulting transient fluid-dynamical equations are formally similar to those of a single-component system, but feature different thermodynamic relations and transport coefficients, which contain the microscopic interactions of all components.
