modelPipeManifoldFlowDistributor
Manifold for heat exchanger register that distributes the mass flow rate equally
Extends from PartialPipeManifold (Partial pipe manifold for a heat exchanger).
Information
This model distributes the mass flow rates equally between all instances
of port_b.
This model connects the flows between the ports without
modeling flow friction.
The model assigns an equal mass flow rate to each element of
port_b.
The model is used in conjunction with
a manifold that
is added to the other side of the heat exchanger registers.
Note: It is important that there is an equal pressure drop in each flow leg between this model, and the model that collects the flows. Otherwise, no solution may exist, and therefore the simulation may stop with an error.
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Integer | nPipPar (from PartialDuctPipeManifold) | Number of parallel pipes in each register | |
| Assumptions | |||
| Boolean | allowFlowReversal (from PartialDuctPipeManifold) | true | = true to allow flow reversal, false restricts to design direction (port_a -> port_b) |
| Initialization | |||
| Modelica.Units.SI.MassFlowRate | mStart_flow_a (from PartialDuctPipeManifold) | Guess value for mass flow rate at port_a | |
Connectors
| Type | Name | Default | Description |
|---|---|---|---|
| Modelica.Fluid.Interfaces.FluidPort_a | port_a (from PartialDuctPipeManifold) | Fluid connector a for medium (positive design flow direction is from port_a to port_b) | |
| Modelica.Fluid.Interfaces.FluidPort_b | port_b (from PartialPipeManifold) | Fluid connector b for medium (positive design flow direction is from port_a to port_b) |
