WebFeb 1, 1998 · Camassa and Holm derived this equation indirectly using an asymptotic expansion in the Hamiltonian of the Euler equations of hydrodynamics. The equation describes the motion of shallow water waves. The global well-posedness of the initial value problem for (1.1) is not yet fully understood, although it is known that for some initial 1 E … WebApr 16, 2013 · We will solve the Euler equations using a high-order Godunov method—a finite volume method whereby the fluxes through the interfaces are computed by solving the Riemann problem for our system. The finite-volume update for our system appears as: Un+1 i=U n + ∆t ∆x Fn+1/2 i−1/2 −F n+1/2 i+1/2 (14) M. Zingale—Notes on the Euler ...
