Investigation of the Meter Factor of Turbine Meter with Unsteady Numerical Simulation

摘要：

The torque balancing equations and the bearing drag torque were deduced in the paper, unsteady numerical simulation is carried out with RNG turbulence model and UDFs (User Defined Functions) in Fluent Code. The meter factors of the turbine meter at different flow rate are calculated by the unsteady numerical simulation. The influence of bearing drag torque is considered. Compared with the calibration experiment, the prediction results based on the numerical simulation showed good agreement. It makes clear that the possibilities to improve the accuracy of the meter and to predicate the meter factor by CFD.
