Finite Element Analysis for Airflow Angular Rate Sensor Temperature Field and Pressure
The airflow angular rate sensor temperature field and pressure were analyzed by finite element method in the sensitive element. Using ANSYS-FLOTRAN CFD software, according to the actual size, building a two-dimensional entity model, the finite element simulation was conducted by a series of procedures, such as meshing, applying loads and solve. Then the temperature field and pressure were calculated in the sensitive element. The compute results show because of the action of heating in parallel placed two hotwires, the hotwires temperature rises around the jet gases, the temperature field produces gradient in the closed cavity; the pressure near the outlet side position is higher than other positions mean value 68%.
