to open the Define Surface Monitor panel.
i. Select Mass Flow Rate from the Report Type drop-down list. ii. Select outlet from the Surfaces selection list.
iii. Click OK to close the Define Surface Monitors panel. (c) Click OK to close the Surface Monitors panel.
4. Initialize the solution from the inlet. Solve /Initialize /Initialize...
(a) Select inlet from the Compute From drop-down list.
(b) Click Init and close the Solution Initialization panel. 5. Save the case file (catalytic . File /Write /Case...
6. Run the calculation by requesting 100 iterations. Solve /Iterate...
(a) Enter 100 for the Number of Iterations. (b) Click Iterate.
The FLUENT calculation will converge in approximately 70 iterations. By this point the mass flow rate monitor has attended out, as seen in Figure . (c) Close the Iterate panel.
7. Save the case and data files (catalytic and catalytic . File /Write /Case & Data...
Note: If you choose a file name that already exists in the current folder, FLUENT will prompt you for confirmation to overwrite the file.
Step 6: Post-processing
1. Create a surface passing through the centerline for post-processing purposes. Surface/Iso-Surface...
(a) Select Grid... and Y-Coordinate from the Surface of Constant drop-down lists. (b) Click Compute to calculate the Min and Max values. (c) Retain the default value of 0 for the Iso-Values. (d) Enter y=0 for the New Surface Name. (e) Click Create.
2. Create cross-sectional surfaces at locations on either side of the substrate, as well as at its center. Surface /Iso-Surface...
(a) Select Grid... and X-Coordinate from the Surface of Constant drop-down lists. (b) Click Compute to calculate the Min and Max values. (c) Enter 95 for Iso-Values.
(d) Enter x=95 for the New Surface Name. (e) Click Create.
(f) In a similar manner, create surfaces named x=130 and x=165 with Iso-Values of 130 and 165, respectively. Close the Iso-Surface panel after all the surfaces have been created.
3. Create a line surface for the centerline of the porous media. Surface /Line/Rake...
(a) Enter the coordinates of the line under End Points, using the starting coordinate of (95, 0, 0) and an ending coordinate of (165, 0, 0), as shown. (b) Enter porous-cl for the New Surface Name. (c) Click Create to create the surface. (d) Close the Line/Rake Surface panel.
4. Display the two wall zones (substrate-wall and wall). Display /Grid...
(a) Disable the Edges option. (b) Enable the Faces option.
(c) Deselect inlet and outlet in the list under Surfaces, and make sure that only substrate-wall and wall are selected.
(d) Click Display and close the Grid Display panel.
(e) Rotate the view and zoom so that the display is similar to Figure . 5. Set the lighting for the display. Display /Options...
(a) Enable the Lights On option in the Lighting Attributes group box.
(b) Retain the default selection of Gourand in the Lighting drop-down list. (c) Click Apply and close the Display Options panel.
6. Set the transparency parameter for the wall zones (substrate-wall and wall). Display/Scene...
