Interfaces.Element1D

Element1D is partial one-dimensional thermal element for models without energy storage.

This partial component provides the basic connectors and variables to create one-dimensional heat transfer models that do not store energy. It defines two thermal connection ports, port_a and port_b. The temperature difference across the element is $\mathrm{\Delta }T$, and the heat flow rate through the element from port_a to port_b is $Q_{flow}$.

The key equations governing its behavior are:

Temperature difference:

$$\mathrm{\Delta }T=port\mathrm{\_}a.T-port\mathrm{\_}b.T$$

Heat flow assignment at ports (assuming $Q_{flow}$ flows from port_a to port_b):

$$port\mathrm{\_}a.Q_{flow}=Q_{flow}$$$$port\mathrm{\_}b.Q_{flow}=-Q_{flow}$$

The relationship for port_b.Q_flow is derived from the model's energy balance equation $mathport\mathrm{\_}a.Q_{flow}+port\mathrm{\_}b.Q_{flow}=0$, which signifies that no energy is stored within the element.

Element1D is partial one-dimensional thermal element for models without energy storage.

This partial component provides the basic connectors and variables to create
one-dimensional heat transfer models that do not store energy. It defines two
thermal connection ports, `port_a` and `port_b`. The temperature difference
across the element is $\Delta T$, and the heat flow rate through the
element from `port_a` to `port_b` is $Q_{flow}$.

The key equations governing its behavior are:

Temperature difference:

math \Delta T = port_a.T - port_b.T

Heat flow assignment at ports (assuming $Q_{flow}$ flows from `port_a` to `port_b`):

math port_a.Q_{flow} = Q_

math port_b.Q_{flow} = -Q_

The relationship for `port_b.Q_flow` is derived from the model's energy balance equation
$math port\_a.Q_{flow} + port\_b.Q_{flow} = 0$, which signifies that no energy is stored
within the element.
