计算围绕中心气泡堆积的等体积气泡的三维簇的能量和形状。由此产生的表面积和气泡压力改进了三维气泡簇的现有生长定律。由于气泡的生长速度主要取决于其面数，因此可以通过考虑气泡拓扑而不是详细的几何形状来加速粗化模拟。因此，可以表征粗化引起的无序泡沫向结垢状态的松弛，其中标准化气泡体积和面数分布保持不变。
The energy and shape of three-dimensional clusters of equal-volume bubbles packed around a central bubble are calculated. The resulting surface areas and bubble pressures provide an improvement upon existing growth laws for three-dimensional bubble clusters. Since a bubble’s growth-rate depends mostly on its number of faces, simulations of coarsening can be accelerated by considering bubble topology rather than detailed geometry. The coarsening-induced relaxation of a disordered foam towards a scaling state, in which the normalised bubble volume and face-number distributions remain invariant, can thus be characterised.
