WebJan 1, 1972 · The first variational principle for the irrotational flow of a compressible fluid is due to Bateman (1929, 1930) [Serrin (1959a) calls it the BatemanDirichlet principle]. Hargreaves (1908) first showed that the pressure integral is a potential of the motion, although he did not use this fact to write a variational principle. WebHow to calculate the first variation of length of a curve γ? The length is defined as L ( γ) = ∫ γ d s. So the first variation is d d c L ( γ + c ϕ) c = 0 = d d c ∫ γ + c ϕ d s c = 0 = ∫ γ + c ϕ ∇ γ + c ϕ ⋅ v c c = 0 (where v c is the velocity of the curve γ + c ϕ ) = ∫ γ + c ϕ v c ⋅ κ c ν c c = 0
