摘要

在这项工作中，我们考虑了自由流动的数值模拟的saint-venant的方程，它形成一个非线性双曲系统的数值解析。数值逼近模型方程采用有限体积法离散化，计算网格为非结构三角形，具有动态自适应能力。采用Roe近似Riemann求解器对数值形容词流进行求解，对龙格-库塔流进行时间积分。源项采用Vazquez上旋格式离散化。

Application of an efficient hydraulic model for surface water flows

In this work, we consider the numerical simulation of free flow by numerical resolution of saint-venant's equations, which form a nonlinear hyperbolic system. The numerical approximation model equation is discretized by the finite volume method, the computational mesh is unstructured triangular and dynamically adaptive. The numerical adjective flows were evaluated by Roe approximate Riemann solver, the time integration is meant for a Runge-Kutta. The source term was discretized by an upwinding scheme of Vazquez.
