摘　　要：目前对于温差流量传感器的研究处于摸索阶段,传感器温度场与流量关系不明确,开展传感器的模拟仿真和试验有助于进一步提高传感器的分辨率和稳定性。为此,通过COMSOL仿真软件对测速传感器温度场进行了仿真分析和试验研究,探究了流量和持水率对测速传感器温度场的影响规律,明确了流量和持水率与时域积分结果的关系。试验结果表明:流量和持水率与积分结果均呈单调递减关系,与仿真结果一致,且在流量0~30 m^(3)/d,持水率0~100%的条件下,测速传感器的分辨率达到了1 m^(3)/d。所得结论可为温差流量检测方法的应用提供理论参考。The research on temperature difference flow sensor is in an exploratory stage for the moment,and the relationship between sensor temperature field and flow rate is not clear,so it is helpful for further improving the resolution and stability of the sensor to carry out simulation and test of sensor.In the paper,the COMSOL simulation software was used to conduct simulation analysis and experimental study on the temperature field of tacho-generator,explore the influence of flow rate and water holdup on the temperature field of tacho-generator,and clarify the relationship between flow rate,water holdup and time-domain integration results.The test results show that the flow rate and water holdup have a monotonically decreasing relationship with the integration results,which is consistent with the simulation results;moreover,when the flow rate is 0~30 m^(3)/d and the water holdup is 0~100%,the resolution of the tacho-generator reaches 1 m^(3)/d.The conclusions provide theoretical reference for the application of temperature difference flow rate detection method.
