Now, inspect the mixture properties resulting from the study. Do so by creating a plot group and plot the results. Start with the density.
Density
1
In the Home toolbar, click  Add Plot Group and choose  1D Plot Group.
2
In the Settings window for 1D Plot Group, type Density in the Label field.
3
Click to expand the Title section. From the Title type list, choose None.
4
In the Density toolbar, click  Global. This adds a Global plot to the Density plot group.
5
In the Settings window for Global, locate the y-Axis Data section. Click Replace Expression  in the upper-right corner and, in the window that opens, either search for Densitypp1, or choose Densitypp1(...)-Density 1 under Model > Global Definitions > Functions. Double-click the expression to add it to the table.
6
In the table, enter the following arguments for the function: Tc, pRef, w_EG, w_W. Make sure to add the arguments in this order. This is the order defined in the Mixture node.
7
Locate the Legends section and find the Include subsection. Clear the Description checkbox.
Note: The function named Densitypp1, can be found in the Model Builder window, under Global Definitions > Thermodynamics. Click the mixture density function, labeled Density 1, and you will find the Function name in the Settings window. The function was created by the Thermodynamic System and can be used in any physics interface.
Now, return to the plot group to improve the plot settings.
1
In the Model Builder window, click  Density.
2
In the Settings window, locate the Plot Settings section.
3
Select the x-axis label checkbox and type Temperature (K).
4
Select the y-axis label checkbox and type Density (kg/m<sup>3</sup>).
5
Click  Plot.
The resulting plot shows the coolant density for the three compositions.
Perform the same steps to complete the plots for viscosity, thermal conductivity, and heat capacity.
