Information

1. Purpose of model

Simple thermal diffusion modeled as energy source using heat port interfaces.

2. Level of detail, physical effects considered, and physical insight

Finite difference approximation of second order (error decreases with square of dx)

3. Limits of validity

You shouldnt use this if the model is not fit for a 1 dimensional discretization!

4. Interfaces

heatPort[N_cv]: Gets the temperatures from the temperature layers and returns the heat flow due to thermal diffusion

5. Nomenclature

The input parameters

6. Governing Equations

(no equations)

7. Remarks for Usage

8. Validation

9. References

This model is largely based on the model "Bouyancy" in the Modelica Buildings-library (https://github.com/lbl-srg/modelica-buildings.git)
