最近的分子动力学模拟的水传输通过内部通道的碳纳米管与水的水库接触表明，传导发生在突发集体水运动。一个连续时间随机游走模型被用来描述一致的运输通过密集的通道充满了分子在一个单一的文件安排，也发现在沸石，以及离子通道和水通道蛋白在生物膜。理论预测的不同集体性质的单文件传输同意模拟结果。
Recent molecular dynamics simulations of water transport through the interior channel of a carbon nanotube in contact with an aqueous reservoir showed that conduction occurred in bursts with collective water motion. A continuous-time random-walk model is used to describe concerted transport through channels densely filled with molecules in a single-file arrangement, as also found in zeolites, as well as ion channels and aquaporins in biological membranes. Theoretical predictions for different collective properties of the single-file transport agree with the simulation results.
