Abstract

We report additional tests of our “extended Lee model” for calibrating turbine meters. The model accounts for 1) Reynolds number (Re) dependent drag and lift, 2) bearing static drag and 3) bearing viscous drag. Initially, we tested this model using a dual−rotor, 2.5−cm−diameter turbine meter and flow measurements spanning a 200:1 range (50  Re  109,000) with liquid mixtures spanning a 42:1 kinematic viscosity range (1.2 × 106 m2 / s  ν  50 × 106 m2 / s). The model correlated the volumetric flow data within 3.6 % over the entire Re range. The same data had a maximum deviation of 17 % from the commonly used Strouhal versus Roshko (or Re) correlation. In this work, we tested the model using three different single−rotor turbine meters with diameters of 2.5 cm, 1.6 cm, and 1.9 cm and flow measurements spanning a 75:1 range (140
