Heat Transfer L2

Created Wednesday 09 April 2014

Base class for heat transfer models with level of detail L2.

1. Purpose of Model


This model provides a basis for modelling the heat transfer between components and/or environments by introducing the general parameters and connectors all heat transfer models with level of detail L2 have in common.

2. Level of Detail and Physical Insight


2.1 Level of Detail

Referring to Brunnemann et al. [1], this model refers to the level of detail L2 because the system is modelled with the use of balance equations, which are spatially averaged over the component.

2.2 Physical Insight

For the description of a heat transferring process information about the temperature and heat flow has to be exchanged between the acting components. This is realized by introducing a heat port. Further information about the location of heat transfer areas and options for the initialization is provided by parameters.

3. Limits of Validity


Not valid without extension

4. Interfaces


4.1 Physical Connectors

5. Nomenclature



6. Governing Equations

The heat transfer area is allocated by the choice of the parameter

7. Remarks for Usage


8. Validation
