Detailed Description

Represents a wall between between two ReactorBase objects.

Walls can move (changing the volume of the adjacent reactors) and allow heat transfer between reactors.

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 133 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 43 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 142 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.

Since: New in Cantera 3.0.

Reimplemented from WallBase.

Definition at line 50 of file Wall.cpp.

◆ heatFlux()

double heatFlux ( ) const

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

Since: New in Cantera 3.0.

inline

Specify the heat flux function $q_0(t)$ .

Definition at line 167 of file Wall.h.

◆ heatRate()

double heatRate ( )

overridevirtual

Heat flow rate through the wall (W).

The heat flux is given by

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

where h is the heat transfer coefficient, A is the wall area, and G(t) is a specified function of time evaluated at the current network time. Positive values denote a flux from left to right.
