Tag: Poiseuille flow

Three inlet velocities, same mesh and solver: maximum velocity and pressure gradient scale as Poiseuille predicts. How to isolate the effect of a boundary condition.

The same laminar channel on three meshes (2,000, 8,000, 32,000 cells): the error against Poiseuille scales with order about 2. How to set up and read a mesh convergence study in OpenFOAM.

First case of the OpenFOAM 14 path: a laminar parallel-plate channel built from scratch with blockMesh, solved with foamRun and validated against the Poiseuille profile (0.15% error).
