Abstract: With this work, we investigate an often neglected aspect of coupled Brownian motors transport, namely, transport coherence. To discuss the transport coherence of coupled Brownian motors, velocity, diffusion coefficient and their ratio (Pe number) are calculated via solving Langevin equation in fluctuating potential ratchet. The results demonstrate that the collective effect of coupled Brownian ratchets can generate high transport coherence. [Copyright &y& Elsevier]
