v7.32.127 WTNP127 — Modeling a water flow in a saturated bar, establishing a steady state

Summary:

This test case represents the modeling of a water flow in a bar subjected to a pressure gradient. A two-phase flow is modelled here and caused to degenerate into a monophasic problem. In this test case, we are interested in establishing the steady state that makes it possible to calculate the outflow of water analytically. The main objective of this test case is to validate the calculation of the integral of hydraulic flows on a surface.
