CONJUGATE HEAT TRANSFER

Conjugate heat transfer is common in many engineering applications, including heat exchangers, HVAC, and electronic component design.

  • Conjugate heat transfer refers to the ability to compute conduction of heat through solids, coupled with convective heat transfer in a fluid.
  • Conduction dominates in solids whereas convections usually dominates in fluids.
  • Coupled boundary conditions are available for wall zones that separates two cell zones.
  • Either the solid zone or the fluid zone, or both, may contain heat source.

The present study demonstrates how to simulate conjugate heat transfer when heat is transferred through multiple solids of different materialswhich are in contact with each other.

For this, some text-user-interface (TUI) commands needs to be activated to slit interior between different solids and to create coupled wall.
