Viscous Vortex Rate Sensor

Abstract

The operation of a flueric vortex rate sensor is discussed for flows in the fully developed range, the range in which the entrance conditions at the periphery of the chamber do not appreciably influence the radial velocity profile throughout most of the chamber. Operation in this range is far different from that in the small boundary layer range usually considered in previous investigations. An intuitive examination shows that the frequency response and rate threshold of the sensor are inferior in the small-boundary-layer range, chosen originally for its desirable gain features.
