It is found that initially uniformly distributed particles can segregate and accumulate to form regularly spaced micron-sized particle clusters. The wavelength of the micro clusters is compared to data formacro-scale sand-ripple patterns and found to obey the sameuniversal scaling as these. A physical and dimensional analysis is performed that confirms the universality of the experimentally observed scaling. The effect of gravity can therefore be discussed on the basis of this universal scaling.Show less >
