In order to include a column of bubbles in your model, your mesh must contain at least one PMesh (a 1D domain within a 2D mesh, or a 1D or 2D domain within a 3D mesh, as shown in Figure 25.2: Bubbling Model with 1D and 2D PMeshes). See PMeshes for information about PMeshes.
Within Ansys Polydata, the inputs for the bubble column are as follows:
Define a nonzero density for the glass material and a nonzero gravitational acceleration.
Material data
Select the Bubbling menu item in the sub-task menu.
Bubbling
In the resulting Bubbling panel, select the PMesh for which you want to define a bubble column.
Click Modify.
Specify the parameters for the bubble column:
Set the radius of the bubbles (
in Theory).
Modify radius of bubbles
Set the density of air (
in Theory).
Modify air density
Set the number of bubbles per unit length (for 1D PMeshes) or area (for 2D PMeshes). This is the value of
in Theory.
Modify bubbles density
If you want to remove a bubble column, select the Delete this column of bubbles menu item.
Repeat these steps for each bubble column you want to define.
