Source

Create Function

create_source(net, junction, mdot_kg_per_s, scaling=1.0, name=None, index=None, in_service=True, type='source', **kwargs)

Adds one source in table net[“source”].

Parameters

• net (pandapipesNet) – The net for which this source should be created

• junction (int) – The index of the junction to which the source is connected

• mdot_kg_per_s (float, default None) – The required mass flow

• scaling (float, default 1) – An optional scaling factor to be set customly

• name (str, default None) – A name tag for this source

• index (int, default None) – Force a specified ID if it is available. If None, the index one higher than the highest already existing index is selected.

• in_service (bool, default True) – True for in service, false for out of service

• type (str, default None) – Type variable to classify the sink

• kwargs – Additional keyword arguments will be added as further columns to the net[“source”] table

Returns

index - The unique ID of the created element

Return type

int

Example

>>> create_source(net,junction=2,mdot_kg_per_s=0.1)

Component Table Data

net.source

Parameter	Datatype	Value Range	Explanation
name	string		Name of the source
junction	integer		Index of connected junction
mdot_kg_per_s	float	\(\geq\) 0	The mass flow injected by the source [kg/s]
scaling	float	\(\geq\) 0	Scaling factor for the injected mass flow
in_service	boolean	True / False	Specifies if the source is in service.
type	string		Type variable to classify sources

Physical Model

A source component injects a specified mass flow into the system. The source is connected to a specified node.

Sources are typically used to model producing units in hydraulic systems. Please note that sources cannot be used to model heat sources for the pandapipes heat mode. In this case, to model a heat flow entering the system, the heat exchanger component can be used.
