Openfoam velocity inlet
Web11 de abr. de 2024 · 8.7 Nonuniform inlet velocity At an inlet boundary, the velocity is usually specified by a fixed value condition , as discussed in Sec. 4.3 . In many CFD applications, the flow at an inlet boundary is described by a single speed which is applied to all faces assuming is uniform across the boundary. WebSince the fluid already has an initial velocity at the inlet in most two-phase flow cases with phase change, the natural convection caused by the density difference is negligible. So, the density of liquid water was assumed to be constant. ... In OpenFOAM-v2006, the “compressible:: ...
