recordflowParametersInternal

Record for flow parameters with prescribed size

Extends from Modelica.Icons.Record (Icon for records).

Information

Data record for performance data that describe volume flow rate versus pressure rise. The volume flow rate V_flow must be increasing, i.e., V_flow[i] < V_flow[i+1]. Both vectors, V_flow and dp must have the same size.

This record is identical to Buildings.Fluid.Movers.BaseClasses.Characteristics.flowParameters, except that it takes the size of the array as a parameter. This is required in Dymola 2014. Otherwise, the array size would need to be computed in Buildings.Fluid.Movers.BaseClasses.FlowMachineInterface in the initial algorithm section, which is not supported.

Parameters

TypeNameDefaultDescription
IntegernNumber of elements in each array
Modelica.Units.SI.VolumeFlowRate[n]V_flowVolume flow rate at user-selected operating points
Modelica.Units.SI.PressureDifference[n]dpFan or pump total pressure at these flow rates
