3.9.3 Analyzing Fiber Variables

You can use ANSYS FLUENT's Plot facilities to analyze fiber solution variables such as fiber velocity, temperature, diameter, etc.

For this you have to generate an xy-file for every variable you want to investigate using the following procedure from the text command interface (assuming that you have already defined a fiber injection):

1.   Store an xy-file with the variable of interest.

continuous-fiber $\rightarrow$ print-xy

2.   Enter the fiber injection of interest when asked for

Fiber Injection name>

3.   Specify a variable for x-column. This will be used as abscissa in the file plot.

4.   Specify another variable for y-column, which will be used as ordinate in the file plot.

5.   Specify a file name when asked for XY plot file name.

6.   Load the file with ANSYS FLUENT's xy plot facilities, described in the ANSYS FLUENT manual.

The following variables can be entered as x-column and y-column:

• axial drag

• conductivity

• curvature

• diameter

• enthalpy

• evaporated mass flux

• heat transfer coefficient

• lateral drag

• length

• mass flow

• mass fraction

• mass transfer coefficient

• Nusselt number

• Sherwood number

• Reynolds number

• specific heat

• surface mass fraction

• temperature

• tensile force

• user variable

• velocity

• velocity gradient

• viscosity

If a fiber injection consists of several fibers, the data of all fibers in this fiber injection will be stored in the xy-file.

In addition to this, you can store a fiber history file for a fiber injection as described in Section  3.6.3. This can be used to analyze a single fiber using ANSYS FLUENT's xy-plot facilities or by external postprocessing programs.
