Hello!
I am trying to develop a solver similar to yours for simulating overland and channel flow. I am having difficulty in developing the critical depth boundary condition at the channel outlet. Have you been able to solve your problem? I need tips for solving the issue. |
A few solutions
Hi All,
I also used the saint-vernant equations in openfoam. I found 3 nice project which helped me out: - avalanche, which solves the equations in the coordinate along the slope and adds a centrifugal force for when the slope changes (https://develop.openfoam.com/Community/avalanche). Note the wrong implementation of the gravity in the shear stress formulations. It should only include the part normal to the bed. - shallowFoam, which is only suitable for low slope angles. It does include depth averaged turbulence, which the previous one lacked (https://github.com/mintgen/shallowFoam). Described in his dissertation: Mintgen, F.: Coupling of Shallow and Non-Shallow Flow Solvers - An Open Source Framework. 2018. PhD dissertation. Technical University of Munich. - Paper by Y Ni, Z Cao, Q Liu called: "mathematical modeling of shallow water on steep slopes" (https://scholar.google.com/scholar?q...n+steep+slopes) |
