IdealHeatTransfer L2
Created Wednesday 09 April 2014
Heat Transfer model assuming an ideal heat transfer
1. Purpose of Model
The temperature values and the occurring heat flow with respect to time are computed for an ideal heat transfer process.
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
In an ideal heat transferring process the heat transfer coefficient tends to infinity. This leads to a temperature difference tending to zero for a finite heat flow rate or to a heat flow rate tending to infinity for a finite temperature difference.
3. Limits of Validity
Only valid for highly effective heat transfer processes
4. Interfaces
The model communicates via outer models and records. Thus its expects to have:
- an outer model named geo as defined Fundamentals:Geometry:GenericGeometry
- an outer record named iCom as defined in Basics:Records:IComBase L2
5. Nomenclature
6. Governing Equations
The volume temperature is set to the heat port temperature
