We have investigated the ripening of breath figures with variable initial order. A dramatic impact of the degree of order on the coalescence behavior is observed. As opposed to the two-droplet coalescence events common to the usual disordered droplet arrays, four-droplet coalescence cascades predominate in a perfectly hexagonal breath figure. Upon introduction of disorder, a gradual transition to a regime dominated by three-droplet cascades is observed. The statistics of coalescence cascades allows for detailed conclusions on the microscopic droplet dynamics.
我们研究了具有可变初始有序度的呼吸图案的成熟过程。观察到有序度对聚并行为有显著影响。与通常无序液滴阵列中常见的双液滴聚并事件不同，在完美六边形呼吸图案中，四液滴聚并级联占主导。引入无序后，观察到逐渐过渡到以三液滴级联为主导的状态。聚并级联的统计数据有助于对微观液滴动力学得出详细结论。
