摘要:: 基于数值仿真软件，对某气流总温传感器进行三维建模及CFD(Computational Fluid Dynamics)仿真分析。该模型描述了气流总温传感器在待测介质中形成绕流流场，以及在周围气流强制对流换热作用下传感器本体的瞬态温度变化。根据计算结果，得到了传感器感温器件表面的温度变化曲线，传感器时间常数以及气流质量流速对时间常数的影响情况。将数值仿真获得的计算值与风洞试验测试所得的实测值进行了对比分析，二者结果较为吻合，变化规律一致，偏差值较小，验证了该文基于CFD数值建模仿真的可行性及有效性。

Abstract:: In this paper,3D-modeling and CFD simulation had been finished for an airflow total- temperature sensor,based on a numerical simulation tool.Some mechanism had been modeled, such as the airflow around the sensor and the transient temperature changing of sensor itself. The result shows that,how the temperature of key sensing surface changes,the sensor time constant,and how to be changed by the air flow rate.Compared with measured value of the wind tunnel test platform,the simulation value showed great anastomosis,and the deviation was low.
