Abstract: It is conjectured that for some physical flow problems there may be
an advantage in following energy exactly as one follows mass elements in the
conventional Lagrangian formulation of fluid dynamics. Essentially, the argument
is a generalization to two dimensions of an idea due to Enig who derived the
equations for one-dimensional slab geometry. The equations are derived both
differentially and integrally from the Eulerian form, and they are compared with
the conventional Lagrangian equations.
