SI Unit Example
|
inject_ID
|
Injector identifier
(Integer, maximum 10 digits)
|
|
unit_ID
|
Optional unit identifier
(Integer, maximum 10 digits)
|
|
inject_title
|
Injector title
(Character, maximum 100 characters)
|
|
Ngases
|
Number of gases
(Integer, 1 < Ngases < 100)
|
|
Iflow
|
Mass vs time function input type flag
(Integer)
= 0: mass is input
= 1: mass flow is input - the input scale factor on time is also applied to mass flow.
|
|
fct_IDM
|
Mass of injected gas vs. time function identifier
(Integer)
|
|
fct_IDT
|
Temperature of injected gas vs. time function identifier
(Integer)
|
|
FscaleM
|
Mass function scale factor
Default = 1.0 (Real)
|
or
|
FscaleT
|
Temperature function scale factor
Default = 1.0 (Real)
|
|
AscaleT
|
Abscissa scale factor for time based functions (Comment 1)
Default = 1.0 (Real)
|
|
mat_IDi
|
Material identifier that identifies the gas (i=1,2…N)
(Integer)
|
|
Molar_Fractioni
|
Molar fraction of injected gas (i=1,2…N)
(Real)
|
|
fct_IDmfi
|
Molar fraction of injected gas vs time function identifier (i=1,2…N)
(Integer)
|
|
|
1. | The sum of Molar Fraction must be 1.0 at any given time. |
2. | The are function identifiers used to define variable molar fraction with time. The function must be defined with the same time abscissa. If > 0, Molar_Fraction is not used. |
