Correct bubblers imported from C-MOLD 2000

Bubblers must be modeled as two beam elements, one to describe the flow of coolant into the bubbler, and the other to describe the flow out of the bubbler.

Bubblers imported from C-Mold 2000 consist of only one beam element and will not be treated correctly by the Cool solver. To correct this problem, follow the steps below.

Note: You may also delete the bubbler imported from C-Mold and build a new bubbler according to the instructions provided in the online help for modeling a bubbler.

A bubbler is modeled using an inner channel element with HTE=0, and an outer bubbler element with HTE=1. Orange is the default color assigned to a bubbler.

1. In the Layers pane, turn off all layers other than the one to which the bubbler was assigned when it was imported.
2. Click on the bubbler to select it and then click (Geometry tab > Properties panel > Assign) to display the Assign Property dialog.
3. Click New and select Channel from the drop-down list.
4. In the Channel dialog, specify the inner diameter of the bubbler, assign a heat transfer effectiveness value of 0, and then click OK twice to apply the new properties.
5. Click (Geometry tab > Utilities panel > Move > Translate).
6. In the model pane, click on the element representing the inner channel of the bubbler.
7. Select Copy and specify a vector that will move the new element away from the part. Click Apply. This will create a copy of the element, which you can easily select and change its properties.
8. Click on the new element to select it and then click (Geometry tab > Properties panel > Assign).
9. Click New and select Bubbler from the drop-down list.
10. In the Bubbler dialog, specify the inner and outer diameters of the bubbler, assign a heat transfer effectiveness value of 1, and then click OK twice to apply the new properties. The inner diameter of the bubbler must be equal to or greater than that of the inner channel.
11. Click (Geometry tab > Utilities panel > Move > Translate).
12. In the graphics pane, click on the new bubbler you have made.
13. In the Move/Copy-Translate dialog, reverse the sign of each of the vector components you specified earlier and click Apply. This will move the element so that the bubbler is superimposed on the channel element.
14. Click (Mesh tab > Mesh panel > Density). Set the mesh density to 2.5 times the diameter of your bubbler. Click Apply and OK.
15. Click (Mesh tab > Mesh panel > Generate Mesh), deselect the check boxes, and click Mesh Now.

Note: You should leave a gap of at least half the diameter of the bubbler between the top of the bubbler and your part. This is to allow clearance for the dome, which forms the top of the bubbler.
