The need of high magnetic field facilities has raised the question of accurate analysis of stability and quench characteristics of forced-flow cooled cable-in-conduit conductor (CICC). The supercritical helium flow is considered in the model of quench propagation in CICC, which is described by Euler equations. In this paper, a scheme named Runge-Kutta discontinuous Galerkin finite element method, was introduced to simulate the quench propagation. We used Gauss-Legendre method to solve the integration in discreted equations, and Lax-Friedrichs fluxes were applied to replace the numerical fluxes at the boundary between elements. The simulated results were compared with experimental data, and they were in good agreement.
