Let’s look at the results from the two study steps just added. Plot the temperature for the glycol/water mixture to reproduce the plots in Figure 9.
Temperature Plot
1
In the Model Builder window, under  Results click  Temperature.
2
In the Settings window for 2D Plot Group, locate the Data section.
3
From the Dataset list, choose Study 4: Glycol and Water /Vel = 1.0 m/s (sol6).
4
In the Temperature toolbar, click  Plot. This generates Figure 9b. Note that the temperature in the apparatus in general is higher than for the case of pure water, mainly due to the lower heat capacity of the glycol/water mixture.
5
From the Dataset list, choose Study 4: Glycol and Water /Vel = 1.15 m/s (sol5).
6
In the Temperature toolbar, click  Plot. This generates Figure 9c. Note now that the increased flow rate reduces the temperature to levels close to the water case.
Next, evaluate the resulting mixture properties within the apparatus. Create three cut line datasets to evaluate the heat capacity throughout the chamber section of the apparatus.
Cut Line 2D 1
1
In the Results toolbar, click  Cut Line 2D.

4
In row Point 2, set r to r_c*0.5.
5
In row Point 2, set z to 1.
6
Locate the Data section. From the Dataset list, choose Study 3: Water/Solution 3 (sol3).
Create two more datasets, one for each solution.
