Abstract
Through the 3D CAD model of a single-jet water meter, a CFD analysis was performed considering flows in laminar, transitional and turbulent regime. The studied water meter is characterized by velocimetric type, whose interaction between the turbine and the impacted jet was studied providing information of physics quantities such as: torque curves, pressure and velocity contours, pressure loss calculation, metrological error curves and angular velocity on turbine according applied flow rate. The mechanical friction between the turbine axis and the bearing is of vital importance, reflecting directly on the sensitivity at low flows rates, such phenomenon was studied and analyzed the contribution at angular velocity on turbine. The results were validated by means of experimental tests did out on test benches.
