VolumeGas L4 Advanced

Created Friday 21 February 2020

Generic finite volume model with 1D discretisation in flow direction.

1. Purpose of Model

2.1 Level of Detail

Referring to Brunnemann et al. [1], this model refers to the level of detail L4 because the system is modelled with the use of balance equations, which are discretised in flow direction. The number of finite volumes N_cv can be set by the user.

2.2 Physical Effects Considered

2.3 Level of Insight

The following physical effects are considered and available at different levels of insight which are implemented as replaceable models.

3. Limits of Validity

• zero flow is not fully supported and will usually cause mass flow chattering and other numerical problems
• no chemical reactions considered
• no gravitational pressure losses

4. Interfaces

5. Nomenclature

7. Remarks for Usage

Option for 2 heat ports.

8. Validation
