NOTES ON BURGERS’S EQUATION - UMD

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. WebConsider the nonlinear convection-diﬀusion equation equation ∂u ∂t +u ∂u ∂x − ν ∂2u ∂x2 =0, ν>0 (12) which is known as Burgers’ equation. This equation is balance between time evolution, nonlin-earity, and diﬀusion. This is the simplest nonlinear model equation for diﬀusive waves in ﬂuid dynamics. http://heath.cs.illinois.edu/iem/pde/burgers/ red and yellow reflective cheveron
