### Madelung equations

(quantum hydrodynamic equations)

The **Madelung equations** are quantum-mechanical (QM) equations in
the form of hydrodynamic equations, merely an alternate means
of carrying out QM calculations suitable for situations where the
fluid characteristics of the material in question are also of
interest (**quantum hydrodynamics**).
