recordEightPortFlowResistanceParameters
Parameters for flow resistance for models with height ports
Information
This class contains parameters that are used to compute the pressure drop in components that have four fluid streams. Note that the nominal mass flow rate is not declared here because the model PartialHeightPortInterface already declares it.
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Flow resistance › Medium 1 | |||
| Boolean | computeFlowResistance1 | true | =true, compute flow resistance. Set to false to assume no friction |
| Boolean | from_dp1 | false | = true, use m_flow = f(dp) else dp = f(m_flow) |
| Boolean | linearizeFlowResistance1 | false | = true, use linear relation between m_flow and dp for any flow rate |
| Real | deltaM1 | 0.1 | Fraction of nominal flow rate where flow transitions to laminar |
| Nominal condition | |||
