This article describes how to define boundary conditions to simulate the complex physics in turbomachinery.


This article includes:
Boundary conditions summary

  • Modeling the 1D duct network
    • Two modeling approaches
    • Convection coupling of duct’s nodes and elements to the rotating wall
    • Convection coupling of ducts inside a 3D solid body
    • Constraining duct temperatures on nodes or elements
  • Modeling thermal contacts
  • Specific convective boundary conditions for turbomachinery
    • Thermal streams
      • Modeling total temperature effects on wall due to rotating flow
      • Connecting thermal streams
    • Thermal voids
    • Thermal convecting zones
  • Protective layers
  • Radiation
  • Structural boundary conditions
