Influence of Thermal Wires Spacing on Fluidic Gyroscope

Abstract:

In this paper, research the influence on spacing thermal wires in the sensitive element of fluidic gyroscope. Using ANSYS-FLOTRAN CFD software, the finite element simulation is conducted by a series of procedures, such as two-dimensional model building of fluidic gyroscope, meshing, loads applying and equation solving. The two-dimensional airflow distributions of different distances between two thermal wires in sensitive element of fluidic gyroscope are calculated. The results show that, when the angular velocity ω_i<20^o/s, and the distance between two thermal wires d=4mm, the structure can reduce the velocity of vortex in sensitive element, and increase the thermal wires variation, thus it will increase bridge output voltage, and improve the sensitivity of fluidic gyroscope.
