Variable Definitions, Ranges and Default Values

The following table shows a brief description of the variables appearing in this tab. The table also displays their default values and their generally acceptable range:

Variable

Default Value

Range

 

○ Flush In Stream
Indicates the input port that is connected to the flush-in stream. If an input stream is already present at the selected port, then the button next to the selection is active. Click on the button to bring up the attached stream’s simulation dialog in order to provide the composition of the material being charged.

<None>

Any Input Port

◙ Volume per Cycle, per Unit (L)
The volume of the flush-in stream per cycle and per unit.

0.0

Positive

◙ Volume Per Filter Area (m3/m2)
The volume of the flush-in stream per filter area.

1.0

Positive

○ Flush Out Stream
Indicates the output port that is connected to the flush-out stream. Click on the list box to bring up a list of available output ports in order to select one.

<none>

Any Output Port

○ Setup Time
The amount of time (per cycle) spent before each operation is carried in preparation for the actual execution of the operation. It may involve actions like cleaning, vacuuming, setting up of equipment, etc. which the user opted not to model explicitly.

0.0

Positive

◙ Flush Time (min)
The actual duration of the operation (per cycle).

15.0

Positive

◙ Flowrate (L/h)
The volumetric flow rate of the flush-in stream.

0.0

Positive

○ Ignore Labor?
Check this box to ignore labor for this operation. This option is used only if the process time is set by a master-slave relationship.

Yes

Yes/No

Symbol Key: ○ User-specified value (always input); ● Calculated value (always output); ◙ Sometimes input, sometimes output

Specification Choices / Comments

The following list describes the available specification choices in this tab; for more details on how these are implemented, see Flush: Modeling Calculations.

•Flush In/Out Streams...

You must specify an input stream as the flush-in stream and an output stream as the flush-out stream.

•Amount...

The volume of the flush-in stream can be the one available in the flush-in stream, or it can be specified on an absolute basis (as volume per cycle and per equipment unit), or it can be specified relative to the area of the filter.

•Flush Time Options...

The user has the option of setting directly the flush time, or the volumetric flowrate of the flush-in stream, or a master-slave relationship.
