Finite Element Analysis of Flow Distribution on Nozzle Array Fluidic Gyroscope Performance

Abstract:

In this paper, the flow distribution in sensitive element of nozzle array structure gyroscope is analyzed. 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, mesh, load applying and equation solving. The two-dimensional airflow distributions of nozzle array structure and normal structure gyroscopes are calculated. The results show that the highest velocity of nozzle array structure fluidic gyroscope is 0.71455m/s at the outlet, which is 47.6% of the nozzle velocity, and velocity is increased by 19.5% than the normal nozzle structure. By using nozzle array structure which can reduce velocity of vortex in sensitive cavity, promote airflow movement, increase temperatures changes and improve the sensitivity of fluidic gyroscope.
