Study 4: Glycol and Water
Enter the settings for the added study. As mentioned, we will use two study steps, both stationary. The output from these studies will result in Figure 6b and c.
Step 1: Stationary
1
In the Settings window for  Step 1: Stationary, locate the Study Extensions section.
2
Select the Auxiliary sweep checkbox.
3
Click  Add twice to add two rows to the table.
4
In the table, enter the following settings:
Parameter name
Parameter value list
Parameter unit
w_EG (Mass fraction, ethylene glycol)
0.527
 
Vel (Pipe inlet velocity)
1
m/s
Add the second step by duplicating the first one.
Step 2: Stationary
1
Right-click Study 4 > Step 1: Stationary and choose Duplicate.
2
In the Settings window for Stationary, locate the Study Extensions section.
3
In the table, enter the following settings:
Parameter name
Parameter value list
Parameter unit
w_EG (Mass fraction, ethylene glycol)
0.527
 
Vel (Pipe inlet velocity)
1.15
m/s
Now enter the needed settings for the two steps.
Step 1: Stationary
1
In the Model Builder window, click  Step 1: Stationary.
2
In the Settings window for Stationary, click to expand the Values of Dependent Variables section.
3
Find the Initial values of variables solved for subsection. From the Settings list, choose User controlled.
4
From the Method list, choose Solution.
5
From the Study list, choose Study 3: Water, Stationary 2.
6
In the Model Builder window, click  Study 4.
7
In the Settings window for Study, type Study 4: Glycol and Water in the Label text field.
8
Locate the Study Settings section. Clear the Generate default plots checkbox.
9
In the Study toolbar, click  Compute.
10
In the Model Builder window, under  Study 4: Glycol and Water >  Solver Configurations >  Solution 5 (sol5) click  Solution Store 2 (sol6).
11
In the Settings window for Solution Store, type Vel = 1.0 m/s in the Label text field.
12
In the Model Builder window, click  Solution 5 (sol5).
13
In the Settings window for Solution, type Vel = 1.15 m/s in the Label text field.
