A variational principle for a fluid with a free surface

  • J. C. Luke (a1)
Abstract

The full set of equations of motion for the classical water wave problem in Eulerian co-ordinates is obtained from a Lagrangian function which equals the pressure. This Lagrangian is compared with the more usual expression formed from kinetic minus potential energy.
