In this paper, Under complex pipeline conditions, the fluid flow field is seriously distorted, which affects the measurement accuracy of the flowmeter. As one of the main components of the flowmeter, the rectifier has an important impact on its measurement accuracy and reliability. Aiming at this problem, the simulation experiments of rectifiers with different structures are carried out in this paper. Firstly, combined with the working principle and structural composition of the turbine flowmeter, the factors affecting the measurement accuracy of the flowmeter are analyzed. Then, the structural model of the rectifier and the pipeline is established, and the flow field distribution in three cases without rectifier, with honeycomb rectifier and with arc rectifier is studied by CFD simulation.The simulation results show that compared with no rectifier, the honeycomb rectifier and the circular arc rectifier have good performance in effectively reducing eddy and turbulent flow, providing more stable and repeated velocity profiles and further improving the flow field distribution. Under the same conditions, the rectification effect of the honeycomb rectifier on the fluid flow field is more significant.This work is very useful for accurate measurement of turbine flowmeter, especially for the complex pipeline conditions.
