摘要

提出了一种新型微流量热分布式质量流量计的管道结构,基于Fluent技术建立管道结构仿真模型,在不同流速下对其温度场进行仿真,得出不同流速下的热量分布。通过MATLab软件画出温差与质量流量的关系图。根据热分布式质量流量计的原理建立流量测量的实验平台。通过实验测量,对比实验结果与仿真结果的数据,确定其在低流速条件下的测量范围,最终达到对传统热分布式质量流量计的应用拓展。
        A pipeline structure of a new micro flow thermal mass flowmeter is described in this paper. The simulation model of the pipeline structure is established on the basis of Fluent. The temperature field is simulated under the conditions of different flow velocities, and the relevant heat distribution is obtained. The relationship graph between temperature difference and mass flow is drawn with MATLAB software. According to the principle of thermal mass flowmeter, the experimental platform is established. By comparing the experiment results with simulation results, the measurement range at low flow velocities is confirmed, and the applications of traditional thermal mass flowmeter are developed.
