THE FLOW INDUCED BY A NEW TYPE OF SELF-PROPELLED VEHICLE IN A DUCT

Abstract

An analysis is carried out to determine the magnitude of the flow velocities that are induced inside a tube in the presence of a vehicle which propels itself by the fore-to-aft transfer, at appropriate rates, of the fluid in the adjacent layers within the tube itself. A fixed schedule of accelerations of the vehicle is considered, with various tube end conditions. The greatest induced air velocities are produced if the tube is open at both ends. If the tube is closed at one or both ends, the induced air velocities are more than an order of magnitude lower. In an infinite or half-infinite tube the induced air velocities are greater than those produced in a closed tube, but still an order of magnitude lower than those produced in a tube open at both ends.
