Minimum energy configurations of small bidisperse bubble clusters

We consider two-dimensional foam clusters consisting of small collections of N bubbles with two different areas. Different arrangements of these bidisperse clusters were found experimentally for each N. Calculation of their perimeter allowed us to compare the energy of each cluster, giving candidates to the minimal energy arrangement. The number of possible clusters is discussed and the calculated energies are compared with existing approximations.
