Finite Element Analysis of Nozzle Dimension Influence on Fluidic Gyroscope Performance

Abstract:

In this paper, research the influence on nozzle dimension in the sensitive element of fluidic gyroscope. Airflow of two different nozzle dimensions is analyzed contrastively 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 nozzle diameters in sensitive element of fluidic gyroscope are calculated. The results show that, compared with large diameter and small diameter nozzle of fluidic gyroscope, airflow velocity in the outlet increases by 10.1%, and 31.3% of velocity in the nozzle in large diameter nozzle. It promotes airflow circulation and reduces airflow accumulation in the sensitive cavity without any vortex increase in large nozzle, it increases thermal wires temperature changes and improves the resolution and sensitivity of fluidic gyroscope.
