Good day. It would be great if somebody could help me.
I`ve got a problem with modeling flow with heat transfer in bottom-hole zone. I`ve got porous media and pipe. All boundary conditions you can see on pictures. (NKT-pipe, POR-porous media) I`ve got this setup for fluent: General: Transient, Pressure-based, 2D Planar. Models: Energy-ON, Viscous-Laminar. Materials: Water liquid. Cell Zone: NKT – water liquid, POR – water liquid porous zone. Porous zone: Direction-1 X:1 Y:0, Relative velocity resistance formulation- ON, Viscous Resistance Dir-1 1e+12 Dir-2 1e+12, Porosity 0.7, Non equlibrium thermal model. Boundary: IN – pressure inlet 1e+7 Pa, OUT – pressure outlet 9e+6 Pa, Temp for both 283 K, HEAT – heat flux 1000. Solution method: Coupled, Pressure PRESTO!, Bounded Second Order Implicit Solution Controls: Courant Number 5, Relaxation Factors 0,5 for both Hybrid Initialization Time Step 0,1 Max Iterations 20 After I set up boundary condition on OUT Fluent show me this message: Warning: Flow boundary zone 14 (same with IN boundary) is adjacent to a solid zone (4). This problem MUST be fixed before solution can proceed. When I try to start calculation, Fluent shut down. How can I solve this problem?
