Simulation of Steady-State Flow in a Constricted Tube with Laminar Viscous Model
I want to simulate a steady-state flow in a constricted tube with laminar viscous model but with increasing Reynolds number or stenosis level, residuals didn't converge.please help me.
We need more information in order to help you :
Dimension 2D or 3D
Mesh quality (Mesh>Info>Quality)
Send us your case if you can
Additional information are
Dimension: axisymmetric flow
Boundary condition: velocity inlet, outflow, wall, axis. I examined another boundary conditions like that mass flow inlet and pressure outlet but residuals didn't converge.
Mesh quality: I used quadrilateral elements. When i simulate the same problem with k-omega SST turbulence model, wall Y Plus obtained under unit (i.e. 0.6).
Please give me an e-mail address until I send my case.
