摘　　要：为了使涡轮流量传感器能保证在气体、黏性介质和小流量等流体条件下有更精确的测量性能,目前科技工作者对涡轮流量计结构的优化与改进做了大量的研究工作,但主要研究集中于传感器叶轮、轴承、非磁电信号检出器等部件的改进与优化方面。由于涡轮流量计内部几何参数较多,各参数对流量计精度影响的机理也各不相同,并且各参数之间存在一定的交互作用,所以本文从各参数的交互作用出发,对涡轮流量计结构参数进行了优化设计,研究各参数对其性能的影响,并利用CFD(计算流体动力学)进行仿真,探究各参数的作用机理,得到一组最优组合。仿真结果表明,仪表系数线性度误差由原来的5.23%降低到4.69%,流量计测量精度显著提高。In order to ensure more accurate measurement performance of turbine flow sensor under the conditions of gas,viscous medium and small flow,scientists and technicians have done a lot of research on the optimization and improvement of the structure of turbine flow meter.However,the main research focuses on the improvement and optimization of sensor impeller,bearing,non-magnetoelectric signal detector and other components.Because there are many geometric parameters in the turbine flowmeter,the influence mechanism of each parameter on the accuracy of the flowmeter is also different,and there is a certain interaction between each parameter.Therefore,based on the interaction of various parameters,this paper optimized the structural parameters of turbine flowmeter and studies the influence of each parameter on the performance.CFD(computational fluid dynamics)was used for simulation to explore the action mechanism of each parameter,and an optimal combination was obtained.The simulation results show that the linearity error of the meter coefficient is reduced from 5.23%to 4.69%,and the measuring accuracy of the flowmeter is significantly improved.
