Format of the user's file:
The file must be in CSV format (in Excel for example) and each column
may be identified by a name (or a number) in the first line. This facilitates
the identification of models' inputs in the next steps of simulation.
In the example presented here, as shown in the figure below, the file
contains the following data given in SI system:
| ROW |
Packing type |
Packing size |
Liquid phase |
Gas phase |
Liquid nature |
General flow regime |
P |
T |
uL |
uG |

-
ROW: line number in the file,
-
Packing type: a code 44 is given to the beads (refer to the section:
Coded
variables). This qualitative variable may be a model's input.
-
Packing size: 0.003 mm is given for the diameter equivalent to a
volume sphere ( for this definition refer to the query
index section in quick guide manual). This quantitative variable is
often used as a model's input.
-
Liquid phase: 3+17+94+95, 2, 99.1+0.8+0.09+0.01.
-
The nature of the liquid used is given by : 3+17+94+95. That
means: 3 for water, 17 for NaOH, 94 for K3FeCN6,
95
for K4FeCN6,
-
the type of composition if more than one component is present: 0
for volume percent , 1 for weight percent or 2 for molar
percent,
-
and the percentage of composition: 99.1+0.8+0.09+0.01.
This means that the liquid used is an aqueous solution of NaOH (0.8% mol.)+K3FeCN6(0.09
% mol.) +K4FeCN6(0.01% mol.)
-
Gas phase : 2,0,100. The gas used is air (code 2) at 100 % vol.
Remark : Liquid and gas composition may be used for comparisons
with data integrated in Multi_R_Designer databank, but not necessary for
simulations (see the example in the Database
section of the quick guide manual).
-
Liquid nature: 1 for coalescing , 2 for foaming. This qualitative
variable is often used as model's input.
-
General flow regime: 1 for low interaction, 2 for high interaction,
3
for transition low to high interaction. This qualitative variable is often
used as model's input.
-
P : pressure
-
T : temperature
-
uL : liquid superficial velocity
-
uG : gas superficial velocity
-
.....
Note: This file may be completed once the inputs
of the models selected are known in the case of manual simulation.
