Solve with Viscous Energy

Add the Viscous Energy model to the simulation and create a scene to track temperature.

  1. Add the Viscous Energy model:
    1. Right-click Physics 1 > Models and select Viscous Energy.
    2. Select Models > Liquid > Polystyrene > Material Properties and set the following properties:
      Node Property Value
      Specific Heat Method Constant
      Constant Value 2000 J/kg-K
      Horizontal Temperature Shift Factor Method Arrhenius
      Arrhenius Activation Energy 52000 J/kmol
      Reference Temperature 413.0 K
    3. Go to Regions > tube > Boundaries > Inlet, select Physics Values > Static Temperature, and set the Value property to 413.0 K.
  2. Create a Temperature Scalar scene:
    1. Right-click Scenes and select New > Scalar.
    2. Rename Scalar Scene 1 to Temperature.
    3. Click the Scene/Plot tab, select Scalar 1 > Scalar Field, and set the property Function to Temperature.
    4. Select Scalar 1 > Parts.
    5. Edit the Parts and select Derived Parts > Plane Section and Plane Section 2.
    6. Select Scalar 1 > Color Bar and set the property Color Map to blue-red-balanced.
    7. Select the Scalar 1 node and set the property Contour Style to Smooth Filled.
Now run the simulation again:
  1. Select Solution > Clear Solution and click OK in the dialog.
  2. Click Run .
  3. Examine the Temperature scene. Move the image to get a view like the one in the following screenshot.

The Temperature scene shows that the temperature of the liquid rises close to the walls of the mixer:
