Journal of Scientific Computing (2016) 69: 122-145. doi:10.1007/s10915-016-0185-x.0885-7474 (print)1573-7691 (online)10.1007/s10915-016-0185-xhttp://hdl.handle.net/2263/56342We consider numerical schemes for 2 2 hyperbolic conservation laws on graphs. The hyperbolic equations are given on the spatially one{dimensional arcs and are coupled at a single point, the node, by a nonlinear coupling condition. We develop high-order nite volume discretizations for the coupled problem. The reconstruction of the uxes at the node is obtained using derivatives of the parameterized algebraic conditions imposed at the nodal points in the network. Numerical results illustrate the expected theoretical behavior.en© Springer Science+Business Media New York 2016.
