Burgers equation breaking time
WebAug 11, 2015 · Viewed 2k times. 4. I am trying to solve the very simple one dimensional burgers equation which is: δ U δ t + δ F δ x = 0. where the flux F of some variable U is defined as. F = U 2 2. If I consider a small control volume around the node i, then I should write the original equation as: U i n + 1 − U i n Δ t + F i + 0.5 n − F i − 0.5 ... WebBurgers' equation is a scalar conservation law with flux f ( q) = q 2 / 2 : (1) q t + ( 1 2 q 2) x = 0. The quasilinear form is obtained by applying the chain rule to the flux term: q t + q q x = 0. This equation looks very similar to the advection equation, with the difference that the advection speed at each point is given by the solution q.
