A NOVEL DESIGN OF PERISTALTIC CARBON NANO PUMP AND AN ANALYSIS OF HELIUM FLOW

A novel nano-scale pump that can transport atoms or small molecules with a peristaltic motion is designed. It proven by molecular-dynamics simulations the introduced nano-pump design works properly. The designed consists of one main carbon nanotube named flow tube and two rotors where multi-walled nanotubes are attached. pumping helium investigated simulations. For varying rotor speeds blade counts, time-averaged velocity, temperature, pressure results pumped calculated, relationships between them modeled as polynomial surfaces. showed frequency increases velocity linearly temperature non-linearly. Furthermore, count proposed mechanism does not substantially affect per previous studies in literature.
