If the flow is irrotational, then ∇ × v = 0. We can introduce a velocity potential, v = ∇ ϕ. Thus, ∇ × v vanishes by a vector identity and ∇ · v = 0 implies ∇ 2 ϕ = 0. So, once again we obtain Laplace’s equation. chkdsk stuck on scanning and repairing 100http://www.columbia.edu/itc/ldeo/lackner/E4900/Themelis5.pdf grass-orch-s.vern-rye-kblu-timWeb1. So actually, the proper form of the conservation law is u t + div x ( ϕ) = 0, where ϕ = u v is the flux. So since this is 1D, you want the total derivative of ϕ with respect to x (where ϕ is understood only as a function of x here.) But in your setting, ϕ is given as a function of u. chkdsk stuck at verifying file acllocation
