modelPowerInterface
Partial model to compute power draw and heat dissipation of fans and pumps
Extends from Modelica.Blocks.Interfaces.BlockIcon.
Information
Block that implements the functions to compute the heat dissipation of fans and pumps. It is used by the model Annex60.Fluid.Movers.BaseClasses.PartialFlowMachine.
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Boolean | motorCooledByFluid | Flag, true if the motor is cooled by the fluid stream | |
| Modelica.SIunits.VolumeFlowRate | delta_V_flow | Factor used for setting heat input into medium to zero at very small flows | |
| Advanced | |||
| Boolean | homotopyInitialization | true | = true, use homotopy method |
Connectors
| Type | Name | Default | Description |
|---|---|---|---|
| Modelica.Blocks.Interfaces.RealInput | etaHyd | Hydraulic efficiency | |
| Modelica.Blocks.Interfaces.RealInput | V_flow | Volume flow rate | |
