Example11 Blocks Set with Discontinuous Boundary

General

  • The “discontinuous” boundary condition is studied in this exercise. The model consists of two blocks contacting each other.
     

  • If bodies are contacting each other, the temperature is usually continuous at the boundary.
    If the “discontinuous” boundary condition is set, the temperature will be discontinuous.
     

  • The temperature distribution and the heat flux vectors are solved.
     

  • Unless specified in the list below, the default conditions will be applied.

Model

Two rectangular solid bodies are in contact each other. The “discontinuous” boundary condition is set at the contact face.

The material is polyethylene. The top and bottom faces are set with the “temperature” boundary condition.

Results

The temperature distribution is shown below.

The right block is 50[deg] all over the body while the temperature distribution is exhibited with the left block.

There is no heat transfer between them.

 

For comparison, the “continuous” boundary condition is set at the contact face. The result is shown below.

The heat transfer is exhibited across the blocks.
