ThreeWayValveGas L1 simple
Created Tuesday 02 February 2016
A model for three way valves with a linear distribution of the mass flow according to the input.
1. Purpose of Model
This model can be used for distributing a mass flow according to the input. No valve characteristic is considered.
2. Level of Detail, Physical Effects Considered and Physical Insight
2.1 Level of Detail
Referring to Brunnemann et al. [1], this model refers to the level of detail L1.
2.2 Physical Effects Considered
- adiabatic
- conservation of mass (no storage, steady flow).
- conservation of energy, no losses, no storage
3. Limits of Validity
- no pressure loss
- no backflow
4. Interfaces
4.1 Physical Connectors
Basics:Interfaces:GasPortIn inlet
Basics:Interfaces:GasPortOut outlet1
Basics:Interfaces:GasPortOut outlet2
4.2 Inputs
- Real Input value for the mass flow distibution.
5. Nomenclature
6. Governing Equations
Energy Balance
No loss of energy and no changes of flow velocity are applied. Therefore, the outlet temperatures are equal to the inlet temperatures.
Mass Balance
The mass balance for steady flow neglecting mass storage and linear distribution according to the split ratio input reads
Chemistry
No chemical reaction is taking place:
Summary
A summary record is available which bundles important component values.
7. Remarks for Usage
- activate or deactive the control signal input by setting splitRatioInput to true
