Sure, I refined the mesh (from 1mm to 0.5mm) and added 5 inflation layers:


Set up details:

  • Energy on
  • SST k-omega mode
  • Setting expressions for water viscosity & density from interpolated data
  • setting tube walls as couppled, copper and assigning 1.2mm wall thickness
  • setting inlets as mass-flow inlets and inputting my mass flow rates and inlet temps.
  • Using tube diameter as reference area (2D problem)

  • Set all residuals to 1e-6
  • hybrid initialisation¬†
  • run calculation

Please let me know if you need anything else, thanks for your time.
