Member Function Documentation

◆ type()

string type ( ) const

inlineoverridevirtual

String indicating the wall model implemented.

Usually corresponds to the name of the derived class.

Reimplemented from ConnectorNode.

Definition at line 116 of file Wall.h.

◆ velocity()

double velocity ( ) const

Wall velocity $v(t)$ at current reactor network time.

Since: New in Cantera 3.0.

Definition at line 48 of file Wall.cpp.

◆ setVelocity()

Definition at line 125 of file Wall.h.

◆ expansionRate()

double expansionRate ( )

overridevirtual

Rate of volume change (m^3/s) for the adjacent reactors.

The volume rate of change is given by

$\dot V = K A (P_{left} - P_{right}) + F(t)$

where K is the specified expansion rate coefficient, A is the wall area, and and F(t) is a specified function evaluated at the current network time. Positive values for expansionRate correspond to increases in the volume of reactor on left, and decreases in the volume of the reactor on the right.

Reimplemented from WallBase.

Definition at line 55 of file Wall.cpp.

◆ heatFlux()

double heatFlux ( ) const

Heat flux function $q_0(t)$ evaluated at current reactor network time.

◆ heatRate()

double heatRate ( )

overridevirtual

Heat flow rate through the wall (W).

The heat flux is given by

$Q = h A (T_{left} - T_{right}) + A G(t)$
