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 WallBase.

Definition at line 141 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 30 of file Wall.cpp.

◆ setVelocity()

void setVelocity ( Func1 f = 0)
inline

Set the wall velocity to a specified function of time, \( v(t) \).

Definition at line 150 of file Wall.h.

◆ vdot()

double vdot ( double  t)
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 F(t) is a specified function of time. Positive values for vdot correspond to increases in the volume of reactor on left, and decreases in the volume of the reactor on the right.

Deprecated:
Still used by traditional MATLAB toolbox; replaceable by expansionRate.

Reimplemented from WallBase.

Definition at line 37 of file Wall.cpp.

◆ 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.

◆ Q()

double Q ( double  t)
overridevirtual

Heat flow rate through the wall (W).

The heat flux is given by
