ON THE MOTION WITHIN FLUID GYROSCOPES,

Abstract

The flow field which results from the disturbance of an initially laminar, viscous, incompressible sink flow through a cylindrical chamber is investigated. The disturbance considered may arise either from an impulsive motion or a harmonic oscillation of the device perpendicular to its axis of symmetry. The results of this investigation indicate the general behavior of the response of the flow field within such a device over a wide range of the governing parameters. In particular, it is shown that the mean time-or phase-lag of the motion is nearly identical with the inviscid transport time, while the mean amplitude of the response is almost proportional to the inverse distance from the axis when the visco-geometric parameter is smaller than 1/10. Hence, such devices may possibly be used to detect extremely small rates of rotation and may act in a certain sense as excellent gyroscopes. (Author)
