TOTAL NUMBER OF EQUATIONS ( 20) TO CALCULATE THE MASS FLOWS
IN THE SYSTEM MUST EQUAL THE NUMBER OF PIPES ( 27).
THE NUMBER OF EQUATIONS IS INCREASED WITH 1 BY SPECIFYING:
* PARAMETER EEQCOD 1 IN STEAD OF 2 (APPARATUS TYPES
"CONDENSER", "HEAT EXCHANGER", "NODE", "COMBUSTOR",
"REFORMER", "FUEL CELL", "MOISTURE SEPARATOR" AND
"GASIFIER")
* PARAMETER DELM FOR A MASS SOURCE OR SINK (A BEGIN OR AN END
OF AN OPEN SYSTEM, RESPECTIVELY)
* A PRODUCTION FUNCTION FOR AN APPARATUS OR A GROUP OF
APPARATUSES
* A SURPLUS POWER FOR A DRIVE TRAIN WITH ONE OR MORE TURBINES
AND ONE OR MORE PUMPS/COMPRESSORS
* PARAMETER LAMBDA FOR A "COMBUSTOR" (WITH EEQCOD=2)
* PARAMETER UOX FOR A "FUEL CELL"
* PARAMETER POWER FOR A "FUEL CELL"
* PARAMETER OFRATI FOR A "GASIFIER"
* PARAMETER SFRATI FOR A "REFORMER" OR A "GASIFIER"
THESE CHANGES DO NOT AFFECT THE SCHEME. CHANGES INCREASING
THE NUMBER OF EQUATIONS WITH 1 BUT ALSO AFFECTING THE SCHEME
ARE:
* REPLACING A "NODE" (WITH EEQCOD=2) BY A "VALVE" (FOR WHICH
ALWAYS A MASS FLOW MUST BE SPECIFIED)
* REPLACING A "HEAT EXCHANGER" (WITH EEQCOD=2) BY A "FLASHED
HEATER" (WHICH WILL ALWAYS CALCULATE ONE OF THE MASS FLOWS
IN THE CONNECTED PIPES)
PLEASE REFER TO THE MANUAL TO SEE THE NUMBER OF EQUATIONS
THAT A CERTAIN APPARATUS TYPE WILL SUPPLY TO THE SYSTEM
MATRIX FOR CALCULATING THE MASS FLOWS IN THE SYSTEM.
