Discussion The Eulerian method of studying fluid motion is not as “natural” as the Lagrangian method since the fundamental conservation laws apply to moving particles, not to fields. 4-8C

scholar.harvard.eduVI-4 CHAPTER 6. THE LAGRANGIAN METHOD 6.2 The principle of stationary action Consider the quantity, S · Z t 2 t1 L(x;x;t_ )dt: (6.14) S is called the action.It is a quantity with the dimensions of (Energy)£(Time). S depends on L, and L in turn depends on the function x(t) via eq. (6.1).4 Given any function x(t), we can produce the quantity S.We’ll just deal with one coordinate, x, …
