Analyzing Results

You examine temperature and pressure on the blade surface.

To analyze results:
Temperature
  1. The temperature at t = 0.001 s, shown in scalar scene Temperature, is as follows:


    The effect of the wake specification at the inlet boundary can be clearly observed on the temperature plot, along with the effect of the phase angle.

  2. Modify the HB Solution View to display the Fourier mode 0 real solution of temperature in the three blade passages:
    1. Select the HB Solution View node and set Mode to Fourier Mode.
    2. Select the Fourier Mode node and make sure that Mode is set to 0, and Output Option is set to Real.


Obtaining XY Plot of Pressure on the Blade Surface

To plot the pressure profile at different time levels on the surface of the blade, it is first necessary to create a derived part that defines the location of the profile.

  1. Right-click Scenes > Mesh Scene 1 and select Open.
  2. Right-click the Derived Parts node and select New > Isosurface.
    The Create Isosurface dialog opens.
  3. Click the menu in Input Parts box.
    The Select Objects dialog appears.
  4. To clear all selections, double-click the Column Selection button in the upper left portion of the dialog.


  5. Expand the Regions > Turbo Blade Row 1 node.
  6. Select Blade Surface Blade Row 1.


  7. Click OK.
  8. Click in the Scalar box and select Block-Mapped 1: Vmin to Vmax.
  9. Enter 0.5 in the iso value text box.
  10. Select No Displayer in the Display section.

    The final panel is as shown below.



  11. Click Create and then Close.
  12. Rename the Derived Parts > isosurface node to Blade 50% Section .
  13. Click (Hide All Meshes).
  14. Click (Make Scene Transparent).

The derived part is shown in the following image for illustration.



This derived part is now used in an XY plot.

  1. Create an HB Solution View on one blade passage for t = 0.001 s.
    1. Right-click the Continua > Harmonic Balance > Models > Harmonic Balance Flow and Energy node and select New HB Solution View.
    2. Select the Solution Views > HB Solution View 2 node and set Mode to Physical Time.
    3. Select the HB Solution View 2 node and set Physical Time to 0.001 s.
  2. Create an x-y plot to display the blade pressure profile.
    1. Right-click the Plots node and select New Plot > X-Y Plot.
    2. Rename the XY Plot 1 node to Blade Pressure Profile.
    3. Select the Blade Pressure Profile node and set the following properties: .
      Property Setting
      Parts Derived Parts > Blade 50% Section
      Representation HB Solution View 2
    4. Select the Blade Pressure Profile > Y Types > Y Type 1 > Scalar Function node and set Field Function to Pressure.

The profile plot appears as shown in the Graphics window.
