Abstract
A rotation transmission nanosystem (RTnS) is an essential component of a nanomachine for transferring an input rotational frequency (ωM) into an output frequency (ωR) via a nanobearing. The ratio of ωR to ωM illustrates the rotation transmission efficiency (RTE) of the system. In this study, a bladed rotor in an RTnS is driven to rotate in a water box. Using the molecular dynamics simulation approach, the water-rotor interaction is investigated. The nanoflow field in the water box is traced. Some remarkable conclusions have been drawn for the design of the nanosystems potentially applied in a nanomachine. For example, the present rotor with uniformly assembled blades guarantees a stable rotation transmission when volume fraction of water Vf > 50%. RTE can be accurately controlled by adjusting the height of the blades. The average rotational frequency of the water cluster is much lower than that of the rotor. When 100% > Vf > 50%, the bubble has breathing vibration that produces the second-order basic frequency of the water cluster.
