摘要：
In this paper, a novel fluid gyroscope based on thermal expansion flow principle was reported. The structural design and sensitive principle were shown. The temperature field and fluid field inside the sensitive component were calculated using COMSOL. Calculation results indicate that temperature inside the sensitive component has a fluctuating growth and form a symmetrically distributed thermal expansion flow driven by 10Hz square wave. When angular rate is applied, the change of temperature difference between the detectors is caused by the flow deflection under the Coriolis force. In the range of +/- 3rad/s, temperature difference rate is 1.56x10(-8) K/rad/s.
