NUMERICAL INVESTIGATION OF FLOW EFFECTS ON ACCURACY IN TURBINE FLOW METERS

• Abstract:

  The present paper describes 2-D numerical simulations of a new class of turbine flow meters with two counterrotating rotors. The main goal was to investigate stator/rotor interactions and to improve the accuracy of the meter. The impact of stator/rotor interaction on the variation of coefficient of tangential force is shown. An improved design with a modified guide vane is proposed. Experimental results of the accuracy curves for the original and the modified guide vane are shown.
