packagePartialWallFriction
Partial wall friction characteristic (base package of all wall friction characteristics)
Extends from Modelica.Icons.Package (Icon for standard packages).
Information
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Boolean | use_mu | true | = true, if mu_a/mu_b are used in function, otherwise value is not used |
| Boolean | use_roughness | true | = true, if roughness is used in function, otherwise value is not used |
| Boolean | use_dp_small | true | = true, if dp_small is used in function, otherwise value is not used |
| Boolean | use_m_flow_small | true | = true, if m_flow_small is used in function, otherwise value is not used |
| Boolean | dp_is_zero | false | = true, if no wall friction is present, i.e., dp = 0 (function massFlowRate_dp() cannot be used) |
| Boolean | use_Re_turbulent | true | = true, if Re_turbulent input is used in function, otherwise value is not used |
