WebMay 13, 2024 · The equations are named in honor of Leonard Euler, who was a student with Daniel Bernoulli, and studied various fluid dynamics problems in the mid-1700's. The equations are a set of coupled differential equations and they can be solved for a given flow problem by using methods from calculus. Web1. 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.
