Step 13: Create a Table to Show Mixing

You can create a table to show how values change at different locations, provided that the locations have been defined. In this section you will create three planes along the mixing region and measure the temperatures on those planes. You will then create a table and define functions that show temperature minimums and maximums, and the differences between those values.

1.   In the 3D Viewer, ensure that only the wireframe is visible.

2.   Click on the +Z axis on the triad to get a side-view of the elbow, then rotate the top of the elbow slightly towards you. This will make it easier for you to see the temperature planes that you will create.

3.   From the tool bar, select Location / Plane. In the Insert Plane dialog box, type Table Plane 1 and click OK.

4.   In the Details view for Table Plane 1, set the following values:

Tab	Field	Value
Geometry	Domains	fluid
	Definition / Method	ZX Plane
	Definition / Y	-6.04
Color	Mode	Variable
	Variable	Temperature
	Range	Local
Render	Lighting	(clear)

5.   Click Apply.

6.   Right-click on Table Plane 1 and select Duplicate. The Duplicate dialog box appears.

In the Duplicate dialog box, accept the default name Table Plane 2 and click OK.

In the Outline view, double-click on Table Plane 2 and change Definition / Y to -0.55. Click Apply.

7.   Repeat the previous step, duplicating Table Plane 2 to make Table Plane 3 and changing Definition / Y to 2.18. Click Apply.

8.   Repeat the previous step, duplicating Table Plane 3 to make Table Plane 4 and changing Definition / Y to 5.04. Click Apply.

Now, create a table:

1.   From the menu bar, select Insert/Table. Accept the default table name and click OK. The Table Viewer opens.

2.   Type in the following headings:

	A	B	C	D
1	Distance to Outlet	Min. Temperature	Max. Temperature	Difference

3.   For the ''Distance to Outlet'' column, create an equation that gives the distance from the outlet (which is at the 8'' mark). Click on cell A2, then in the Table Viewer's Insert bar, select Function / CFD-Post / minVal. In the cell definition field you see =minVal()@, which will be the base of the equation. With the cursor between the parentheses, type Y. Move the cursor after the @ sign and either type Table Plane 1 or select Insert / Location / Table Plane 1. The expression you have created gives the value of Y for Table Plane 1. To determine the distance of Table Plane 1 from the outlet, complete the equation as follows, being careful to add 8[in]- to the beginning of the equation to set the location of the outlet:

=8[in]-minVal(Y)@Table Plane 1

When you click away from cell A2, the equation is solved as 1.404e+01 [in].

4.   Complete the rest of the table by entering the following cell definitions:

	A	B	C	D
1	Distance to Outlet	Min. Temperature	Max. Temperature	Difference
2	=8[in]-minVal(Y)@Table Plane 1	=minVal(T)@Table Plane 1	=maxVal(T)@Table Plane 1	=maxVal(T)@Table Plane 1- minVal(T)@Table Plane 1
3	=8[in]-minVal(Y)@Table Plane 2	=minVal(T)@Table Plane 2	=maxVal(T)@Table Plane 2	=maxVal(T)@Table Plane 2- minVal(T)@Table Plane 2
4	=8[in]-minVal(Y)@Table Plane 3	=minVal(T)@Table Plane 3	=maxVal(T)@Table Plane 3	=maxVal(T)@Table Plane 3- minVal(T)@Table Plane 3
5	=8[in]-minVal(Y)@Table Plane 4	=minVal(T)@Table Plane 4	=maxVal(T)@Table Plane 4	=maxVal(T)@Table Plane 4- minVal(T)@Table Plane 4
6	=8[in]-minVal(Y)@ pressure outlet 7	=minVal(T)@ pressure outlet 7	=maxVal(T)@ pressure outlet 7	=maxVal(T)@ pressure outlet 7- minVal(T)@ pressure outlet 7

As you complete the table, notice that the minimum temperature values stay constant, but the maximum values decrease as mixing occurs.

Note:    The sixth row determines the values at the outlet, rather than on a plane you defined.

5.   The default format for cell data is appropriate for some variables, it is not appropriate here. Click on cell A2, then while depressing the Shift key, click in the lower-right cell (D6). Click on the Number Formatting icon icon in the Table Viewer toolbar. In the Cell Formatting dialog box, set Precision to 2, change Scientific to Fixed, and click OK.
