Evolvement of bubble size distribution of aluminum foams with different bubble structure models is studied based on the MacPherson’s theory for coarsening of three-dimensional microstructures. Numerical predictions reveal that the changing way of the foam’s mean volume follows the relationship , which agrees with MacPherson. It is found that the foam’s structure model has a dramatic effect on the bubble mean volume change, i.e., bubbles with cubic form are shrinking with time, while bubbles with icosahedrons form will be coarsening. Surface tension plays a dominative role in the changing processes of bubble volume distribution of foams.
