Detailed Description

Adiabatic, reversible flow in a constant-area duct.

Constructor & Destructor Documentation

Default constructor.

virtual ~FlowReactor ( )


Definition at line 31 of file FlowReactor.h.

Member Function Documentation

void initialize ( doublereal  t0 = 0.0)

Initialize the reactor.

Must be called after specifying the (and if necessary the inlet mixture) and before calling advance.

Reimplemented from Reactor.

Definition at line 42 of file FlowReactor.cpp.

References ReactorBase::m_nsp, and Phase::restoreState().

void updateState ( doublereal *  y)

Set the mixture to a state consistent with solution vector y.

Reimplemented from Reactor.

Definition at line 49 of file FlowReactor.cpp.

References Phase::saveState(), Phase::setMassFractions(), ThermoPhase::setState_HP(), and ThermoPhase::setState_TP().

void insert ( G &  contents)

Insert something into the reactor.

The 'something' must belong to a class that is a subclass of both ThermoPhase and Kinetics.

Definition at line 72 of file Reactor.h.

References ReactorBase::setThermoMgr().

void setEnergy ( int  eflag = 1)

Set the energy equation on or off.

Definition at line 92 of file Reactor.h.

void setInitialVolume ( doublereal  vol)

Set the initial reactor volume.

By default, the volume is 1.0 m^3.

Definition at line 56 of file ReactorBase.h.

void setInitialTime ( doublereal  time)

Set initial time.

Default = 0.0 s. Restarts integration from this time using the current mixture state as the initial condition.

Definition at line 66 of file ReactorBase.h.

References ReactorBase::time().

void setThermoMgr ( thermo_t thermo)

Specify the mixture contained in the reactor.

Note that a pointer to this substance is stored, and as the integration proceeds, the state of the substance is modified.

Definition at line 40 of file ReactorBase.cpp.

References ThermoPhase::enthalpy_mass(), ThermoPhase::intEnergy_mass(), ReactorBase::m_nsp, Phase::nSpecies(), ThermoPhase::pressure(), and Phase::saveState().

Referenced by Reactor::insert().

virtual void advance ( doublereal  time)

Advance the state of the reactor in time.

timeTime to advance to (s). Note that this method changes the state of the mixture object.

Definition at line 111 of file ReactorBase.h.

thermo_t& contents ( )

return a reference to the contents.

Definition at line 125 of file ReactorBase.h.

doublereal time ( ) const

the current time (s).

Definition at line 144 of file ReactorBase.h.

Referenced by ReactorBase::setInitialTime().

doublereal volume ( ) const

Returns the current volume of the reactor.

Return the volume in m**3

Definition at line 153 of file ReactorBase.h.
