Abstract:
In this paper, the airflow of two different chamber structures is analyzed contrastively in the sensitive element of fluidic gyroscopes. 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, we calculate the two dimensional airflow distribution of rectangle chamber and streamline chamber in sensitive element of fluidic gyroscope. The results show that the airflow velocity of the exit section in the streamline chamber which is 28.87% of the nozzle velocity is higher than that in the rectangle chamber structure, so the streamline chamber structure brings airflow together to a certain extent, and it also reduces the airflow accumulation in the chamber and smoothes airflow within the loop channel, lastly velocity gradient change in the streamline chamber is greater than that in the rectangle chamber, and the resolution of fluidic gyroscope is better than that with rectangle chamber.
