HeatStructure2DCoupler

This component couples two 2D heat structures via a heat transfer coefficient.

Usage

This component has the following restrictions:

  • The coupled heat structures must be 2D heat structures.

  • The coupled heat structures must be of the same type.

  • Only one boundary name may be provided in each of the "primary_boundary" and "secondary_boundary" parameters.

  • The meshes along the coupled boundaries must be aligned. Each element on a boundary is paired with the nearest element on the coupled boundary. The alignment check requires that each element on a boundary has exactly one element from the coupled boundary paired to it.

Advanced Parameters

Formulation

The heat conduction equation is the following: where

  • is density,

  • is specific heat capacity,

  • is thermal conductivity,

  • is temperature, and

  • is a volumetric heat source.

Multiplying by a test function and integrating by parts over the domain gives where is the boundary of the domain .

For Neumann boundary conditions on the boundary , is replaced with a known incoming heat flux function :

For the heat structure , the incoming boundary heat flux is computed as

where

  • is the heat transfer coefficient,

  • is the surface temperature of the heat structure ,

  • is the surface temperature of the coupled heat structure , and

  • is the area scaling factor of the heat structure :

where is the area of the heat structure boundary .
