采用有限体积法在一维网络上离散了基于浅水方程的水动力过程模型。在有限体积的基础上,用一致有限体积结模型代替了代数耦合条件。我们对一步龙格-库塔格式使用离散伴随计算来生成快速、鲁棒的梯度。我们用下降法对一个实例网络进行了最优控制,并讨论了计算结果。
A hydrodynamic process model based on shallow water equations is discretized on 1D-networks with the method of finite volumes. Based on the finite volumes we replace algebraic coupling conditions by a consistent finite volume junction model. We use discrete adjoint computation for one step Runge-Kutta schemes to generate fast and robust gradients for descent methods. We use the descent methods to generate an optimal control for an example network and discuss the computational results.
