Detailed Description

Vertex model to represent a general purpose separator with many inlets and nOutlets >= 2 outlets.

The nOutlet option (the number of outlets) must be supplied at construction time and has default value 2.
Performs an arbitrary separation as specified.
Separation yields are fixed by setting the splits for all components in the
first nOutlets - 1 streams.

For example in the case of nOutlets == 2 and NCOMPONENTS == 3 :

Q("Spl.outSplit[0][0]").set(0.25);
Q("Spl.outSplit[0][1]").set(0.95);
Q("Spl.outSplit[0][2]").set(0.05);

these same variables can also be assigned:

MAKEASSIGNMENT(Q("Sep.outSplit[0][0]"); One - splitPar, "Separation of component 1 to stream 1"); \n
MAKEASSIGNMENT(Q("Sep.outSplit[0][1]"); One - splitPar, "Separation of component 2 to stream 1"); \n
MAKEASSIGNMENT(Q("Sep.outSplit[0][2]"); One - splitPar, "Separation of component 3 to stream 1"); \n

whereas outSplit[nOutlets - 1][*] are calculated and can neither be set nor be assigned.

List of ports:

in inlet to Separator
out1, out2, ... outlet of each stream from Separator

#include <libpf/units/Separator.h>

Remarks

Warning: Requires the list of components to be populated before the construction; Thread safe:; Extendable:; Platform dependencies:

void Separator::initializeNonPersistents ( void )

inlineoverridevirtual

estimates hidden, non-persistent unknowns from the current results

Implements Model.

void Separator::normalize_ ( void )

protected

normalize input outSplit

ObjectiveNleAd * Separator::objectiveFunction ( void )

inlineoverridevirtual

returns a pointer to the model's objective function

Implements Model.

		0.	9,
		""
	)

◆ QUANTITY() [2/8]

Separator::QUANTITY	(	deltaP	,
		"Overall pressure drop"	,
		0	,
		"Pa"
	)

◆ QUANTITY() [3/8]

Separator::QUANTITY	(	deltaPMax	,
		"Maximum allowable pressure drop"	,
		0.	0,
		"Pa"
	)

◆ QUANTITY() [4/8]

Separator::QUANTITY	(	duty	,
		"Duty inlet-outlet"	,
		0	,
		"W"
	)

◆ QUANTITY() [5/8]

		"Flow coefficient"	,
		1000.	0,
		"kg/m7"

◆ setup()

void Separator::setup ( void )

inlineoverridevirtual

performs initializations required immediately before solution

Implements Model.

◆ setup_of()

void Separator::setup_of ( void )

overridevirtual

setup and resize appropriately internal vectors; must be provided by implementations

Implements ObjectiveNleAdVertex.

◆ STRING()

Separator::STRING	(	option	,
		"Pressure option: {DPKS}"	,
		"P"
	)

Pressure option: {D,P,K,S}

D assumes the overall deltaP is fixed
P assumes the outlet pressure is fixed (default)
K assumes the flowcoefficient is fixed
S assumes deltaPstream are fixed

◆ testconnect_()

void Separator::testconnect_ ( void )

protected

test consistency and stream connectedness; initialize inletstreams_ and outletstreams_

◆ type()

const std::string & Separator::type ( void ) const

inlineoverridevirtual

Returns: the C++ name of the class the instance belongs to

Note: it is the responsibility of the caller to not access this reference after the lifecycle of the Item

Reimplemented from Object.
