class HeatFlux(rc_solution: RCSolution = <pyrc.core.components.templates.RCSolution object>)#

Bases: object

boundary(boundary: BoundaryCondition, time_step_index=None)#
calculate_heat_flux(node, resistors: list | Resistor, time_step_index=None) → np.ndarray | float#

Returns the heat flux going into the node by the passed resistors.

Parameters:

  • node (NoteTemplate) – The Node of which the heat flux is being calculated.

  • resistors (list | Resistor) – The resistors used to calculate the heat flow.

  • time_step_index (int | slice | list, optional) – The time steps that should be calculated. If None, all are calculated.

Returns:

The heat fluxes for every time step.

Return type:

float | np.ndarray

heat_flux_directions(nodes: list[Node], directions: list | np.ndarray = array([0, 0, -1]), except_resistor_types=None, time_step_index=None) → tuple | np.ndarray#

Returns the heat flux through the layer in the desired direction of all nodes in the given list.

E.g. if the direction is (0,0,1) the heat flux in positive z direction is calculated. The heat flux is positive if going in the same direction as the desired one.

Parameters:

  • nodes (list[Node]) – The Nodes of which the heat flux is being calculated.

  • directions (list | np.ndarray, optional) – The direction(s) in which the heat flux is calculated. Can be a list then each direction is calculated and returned.

  • except_resistor_types

  • time_step_index

Returns:

The result of one direction as np.ndarray or the result of all directions as tuple.

Return type:

np.ndarray | tuple

internal_heat_source(ihc: InternalHeatSource | list, time_step_index=None)#
parse_time_step_index(time_step_index)#
preheat(distributor: MassFlowNode, collector: MassFlowNode)#

Returns the preheat in Kelvin.

Return type:

np.ndarray

fluxes_data(boundaries: list = None, boundaries_sum: list = None, time_step_index=None, balance: bool = False, rc_solution: RCSolution = None)#
get_accumulated_heat_flux(node: Capacitor)#

Sums up the heat flux of all connected resistors.

Used to get the heat flux that is brought in through BoundaryCondition s.

Parameters:

node (NoteTemplate) – The Node of which the heat flux is being calculated. For this, all connected resistors are summed up.

Returns:

The heat flux of all connected resistors.

Return type:

float

plot_channel_balance(channel_nodes: list[Node] | ChannelNode, distributor: MassFlowNode, collector: MassFlowNode, time_step_index=None, start_date=datetime.datetime(2023, 1, 1, 0, 0), y_scale=1)#

Plots the balance of the given channel nodes.

Parameters:

  • channel_nodes (list[ChannelNode] | ChannelNode) – The channel nodes to plot the sum of.

  • distributor (MassFlowNode) – The distributor before the channel nodes. Used to calculate the heat flux that goes into the mass flow within the channel nodes.

  • collector (MassFlowNode) – The collector after the channel nodes. Used to calculate the heat flux that goes into the mass flow within the channel nodes.

  • time_step_index (int | slice | list, optional) – The time steps that should be calculated.
