The challenge in transporting water molecules through one-dimensional, large, disjoint nanochannels arises from the breaking of the water bridge. Even under significant pressure differences, water molecules are difficult to transport through these large disjoint nanochannels. Restoring the broken water bridge is crucial for maintaining continuous water transport through disjoint nanochannels. Current repairing methods, including the application of uniform or terahertz electric fields, are passive solutions. Once the electric fields are removed, it will stop working, causing the bridge to break again. In this study, molecular dynamics simulations are employed to investigate water transport through disjoint nanochannels with large nanogaps mediated by the coverage of coaxial nanochannels. The results reveal that as the diameter of the covered nanochannel decreases, the peak interaction between water molecules and the nanochannel decreases, which facilitates the reformation of the water bridge within the nanogap region. The water transfer rate through the disjoint nanochannel exhibits a non-monotonic dependence on the covered nanochannel diameter: it increases rapidly initially, then decreases with further increase in diameter, eventually reaching a relatively stable flow rate. Increasing the diameter of the covered nanochannel enhances water occupancy within the disjoint nanochannel, while the velocity and order parameter of water molecules display an initial increase followed by a decrease with further increase in diameter. These results offer significant insights into understanding the influence of covered nanochannels on water transport through disjoint nanochannels andproviding novel approaches for repairing broken water bridges in disjoint nanochannel systems.
