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.

Definition at line 25 of file Wall.h.

Member Function Documentation

vdot()

doublereal vdot ( doublereal  t )

virtual

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.

Definition at line 36 of file Wall.cpp.

References Func1::eval(), and ReactorBase::pressure().

Q()

doublereal Q ( doublereal  t )

virtual

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. Positive values denote a flux from left to right.
