摘　　要：该文提出具有方向选择性并通过热平衡检测流速的方法,隔热套管与流体接触面之间平行安装,并保持有一特殊距离,实现方向选择性,通过检测流体接触面的温度来测量流体流速。用这种方法研制了一种单方向流速测量传感器,扩展用于构成三维风速传感器。该传感器可广泛应用于风力发电、气象预报、空间飞行器、工业锅炉等领域的气体和液体速度场、流量场测量。It is suggested in this paper that a new method of detecting fluid speed has directional selectivity and thermal equilibrium.In order to have further of directional selectivity,the adiabatic bushing is parallel installed with the fluid interface and keep with a special distance.The flow speed can be detected by measurement the temperature of the interface between fluid and sensor.A single aspect fluid speed sensor was developed and was used to designing a three-dimensional wind speed sensor.It can be widely used in wind power,weather forecasting,space vehicles,industrial boilers,and other fields of gas velocity,flow-field measurements.
