摘　　要：为了研究6DOF模型应用于涡轮流量计流体仿真的可行性,利用FLUENT软件对涡轮流量计内流场进行仿真计算。研究中获得三种规格涡轮流量计在不同工况下的仪表系数,与校准试验结果相比较,最大差别约为3.8%,仿真与校准两者结果一致性较好,表明6DOF模型用于涡轮流量计仿真具有较好的可行性。To study the feasibility of applying the 6D0F model to the turbine flowmeter flow simulation,FLUENT software was used to simulate the flow field in the turbine flowmeter.In this study,the K-factor of three types of turbine flowmeter under various working conditions was obtained.Compared with the calibration test results,the maximum deviation is about 3.8%.The results of the simulation are in good agreement with calibration,which indicates that the 6 DOF model is feasible for turbine flowmeter simulation.
