Step 9: Postprocessing

1.   Display the pressure field in the fluidized bed (Figure  23.6).

Graphics and Animations Contours Set Up...

(a)   Select mixture from Phase drop-down list.

(b)   Select Pressure... and Static Pressure from the Contours of drop-down lists.

(c)   Click Display.

Figure 23.6: Contours of Static Pressure

  Note the build-up of static pressure in the granular phase.

2.   Display the volume fraction of solids (Figure  23.7).

(a)   Select solids from the Phase drop-down list.

(b)   Select Phases... and Volume fraction from the Contours of drop-down lists.

(c)   Click Display and close the Contours dialog box.

(d)   Zoom in to show the contours close to the region where the change in volume fraction is the greatest.

  Note that the region occupied by the granular phase has expanded slightly, as a result of fluidization.
