Meshing and CFD Accuracy - ICM

Case Study: Laminar Flow Through a Pipe
with Stenosis (1)
• The stenosis has an axisymmetric constriction of
sinusoidal shape.
– The length of the constriction (L c ) is four times the pipe
diameter.
• The inlet flow is a fully-developed laminar flow.
• Two Reynolds numbers (Re D = 50, 100) were
considered.
• Three different meshes were used.
– Quad mesh
– Coarse tri mesh
– Fine tri mesh
