.. _section-5.13.1:
Input Description
~~~~~~~~~~~~~~~~~
The input description can be divided into the input needed for the
PRIMAR-1 option and the input needed for the PRIMAR-4 option.
.. _section-5.13.1.1:
PRIMAR-1 Option
^^^^^^^^^^^^^^^
For the PRIMAR-1 option two variables need to be supplied for INPCOM (Block 1)
and all the variables for PRIMIN (Block 14). The two variables for INPCOM are
:sasinp:`NPRES` and :sasinp:`IPRION`.
.. _section-5.13.1.2:
PRIMAR-4 Option
^^^^^^^^^^^^^^^
For the PRIMAR-4 option, one variable needs to be supplied for INPCOM (Block 1),
eight variables for PRIMIN (Block 14), and all of the variables for INPMR4 (Block 3) and
PMR4IN (Block 18) that are appropriate for the model being considered. The one variable
for INPCOM is :sasinp:`IPRION`. The eight variables for PRIMIN are
.. list-table::

* - :sasinp:`TIMMIX`

INPMR4 contains the integer input for PRIMAR-4 and PMR4IN contains
the floating-point input, as described in the input listing in :numref:`Chapter %s<section-2>`. Only input information pertinent to the model being calculated needs
to be entered. For example, if no intermediate loop is present, no
information for the intermediate loop in either INPMR4 or PMR4IN
need be entered. Any variable not entered is assumed to be zero, since
all of the input blocks are zeroed out before any input information is
read in. Also, any extraneous information, which may be left over from
an old input deck is ignored, provided all entries are made correctly.
That is, if the number of compressible volumes in an intermediate loop
is entered as zero, then any compressible volume information supplied
for that intermediate loop will be ignored.
An example of INPMR4 and PMR4IN input, the integer and
floating-point input blocks for PRIMAR-4, is shown below for the example
used in :numref:`section-5.13.2`.

Example of a Primary Loop
~~~~~~~~~~~~~~~~~~~~~~~~~
As an aid to the user in preparing PRIMAR-4 input data, the primary loop
in :numref:`figure-5.13-1` is described.
.. _figure-5.13-1:
.. figure:: media/image16.png
:align: center
:figclass: align-center
Example of a Primary Loop.
This primary loop consists of five compressible volumes, CV1,...,CV5,
five liquid segments, S1,...S5, fourteen elements, E1,...,E14,
distributed among the liquid segments, nine temperature groups,
T1,...,T9, of liquid flow elements, and three gas segments. The
compressible volumes are:
CV1 = inlet plenum
CV2 = outlet plenum with cover gas
CV3 = pump bowl and cover gas
CV4 = compressible gas volume, no liquid
CV5 = compressible gas volume, no liquid
The elements are:
E1 = core subassemblies
E2, E4, E5, E7, E8, E10, E12, E13, E14 = pipes
E3, E6 = bypass channels
E9 = pump impeller
E11 = shell side of intermediate heat exchanger
The elements in liquid segment S5, for example, are E9, E10, E11, E12,
E13, and E14.
The assumed directions of flow for the liquid, as well as for the gas,
segments are indicated in the diagram. It is this assumed direction of
flow that is used in choosing the inlet and outlet compressible volumes
for a liquid or for a gas segment. For example, CV3 is the inlet
compressible volume and CV1 is the outlet compressible volume for liquid
segment S5, while CV3 and CV4 are the inlet and outlet compressible
volumes for gas segment G2. It is also with respect to the assumed
directions of the segments that positive and negative flow rates are
interpreted. Finally, it should be observed that positive inlet flow to
a liquid or gas segment is flow out of the compressible volume at the
segment inlet.
The multiplicity of 3 that appears in :numref:`figure-5.13-1` where G2 joins CV4,
where E8 joins CV2, and where E14 joins CV1 is present because in this
example there are actually three identical primary loops attached to the
respective compressible volumes, and instead of performing three
identical calculations, the code computes one primary loop and
multiplies the appropriate flows by 3. It should be noticed, however,
that the multiplicity for liquid segment S4 is 3 at the inlet and 1 at
the outlet, for liquid segment S5 it is 1 at the inlet and 3 at the
outlet, and for gas segment G2 it is 1 at the inlet and 3 at the outlet.
The multiplicity for all other liquid and gas segments must be set to 1
at both ends.
The liquid temperature calculations, which are performed after the
liquid flow calculations have been completed, are done by temperature
groups. This allows for the grouping of adjacent elements whose
temperatures are computed in a similar way, such as elements E12, E13,
and E14, all of which are pipes in temperature group T10, and also
elements E9, and E10, a pump and connecting pipe, in temperature group
T8. Where such grouping is inappropriate, a single element comprises a
temperature group, such as the bypass channels as T2 and T5 and the
intermediate heat exchanger as T9.
Although not shown in the figure, if an intermediate loop were to be
added, it would be structured in a fashion similar to the primary loop,
and it would contain an element representing the tube side of the
intermediate heat exchanger and would be located next to E11 in the
diagram.

Output Description
~~~~~~~~~~~~~~~~~~
The PRIMAR output information is largely self-explanatory. Specimens of
three output printouts for the example in :numref:`section-5.13.2` are displayed.
The first is an input edit in which all of the input variables in Blocks
3 and 18 are echoed back. The second is a print of the steady-state
values calculated by the PRIMAR steady-state routines. Finally, the
third is the print of the values calculated by the transient routines at
a later time step.

Plotting PRIMAR-4 Data
~~~~~~~~~~~~~~~~~~~~~~
The PRIMAR4.dat binary output file is created by the PRIMAR-4 module
when the input parameter NBINOT > 0. Data written to PRIMAR4.dat can be
extracted with the PRIMAR4toXML utility which converts PRIMAR4.dat from
binary to an XML spreadsheet. The XML spreadsheet can be imported into
Microsoft Excel for convenient post-processing.
Once imported into Microsoft Excel, the XML version of PRIMAR4.dat will
contain one row for each time step that was printed. The first few
columns provide information related to the time, and the remaining
columns provide the results of the variables selected in the IBINTOT
array. They are in the same order that they are input, e.g. from K = 1
to NBINOT. In particular,
- Column A: ISTEP time step number
- Column B: IPRSTP printed time step number
- Column C: Time (sec)
- Column D: Data associated with IBINOT(1)
- Column E: Data associated with IBINOT(2)
- And so on up to IBINOT(NBINOT)
Unlike other binary output files, only user-selected data appears on
PRIMAR4.dat. That is, if you do not request a particular data item (e.g.
liquid segment flow rate) to be written, then it will not appear in
PRIMAR4.dat. The user selects the data items in the INPMR4 input block
(Block 3) using inputs :sasinp:`NBINOT`, :sasinp:`IBINST`, :sasinp:`IBINOT`, and :sasinp:`INULLT`. The input specifications are shown in
:numref:`table-A2.2-1`. The appropriate values for IBNTYP and INUM for each
available variable are provided in :numref:`table-A2.2-2`.
