| Abstract: | We derive general equations relating the surface energy of strained bubble clusters to the volumes and pressures in the bubbles. These equations generalize a similar equation for free bubble clusters. We apply the equations to periodic clusters, clusters between two parallel walls and clusters enclosed by a wall. |
