In fluiddynamics, Luke's variational principle is a Lagrangian variationaldescription of the motion of surface waves on a fluid with a freesurface, under the action of gravity. This principle is named after J.C.Luke, who published it in 1967. This variational principle is forincompressible and inviscid potential flows, and is used to deriveapproximate wave models like the so-called mild-slope equation, or usingthe average-Lagrangian approach for wave propagation in inhomogeneousmedia. Luke's Lagrangian formulation can also be recast into aHamiltonian formulation in terms of the surface elevation and velocitypotential at the free surface.VDM Verlag, Dudweiler Landstraße 99, 66123 Saarbrücken 72 pp. Englisch.
