cross section triangle
Two-phase flow of a single bubble in a triangular channel. The Navier-Stokes equations are discretized through the Arbitrary Lagrangian-Eulerian framework in which the interface between fluids are accessed sharply by defining a triangular surface embed on the tetrahedral mesh. In such a particular simulation, the confi ned bubble is deformed due to the wall efects and its shape corresponds to the cross section shape of the channel. Three views are available to look in details the flow: single bubble side view, rear view and a cut plane along the channel which describes the remeshing methodology of the outer tetrahedron mesh.
