Abstract: The flow of a viscous fluid through a straight measuring tube of a coriolis flowmeter was investigated using numerical simulations. Numerical simulations were performed by the Comet code, which is based on the finite volume method. The simulations were made for various Reynolds numbers at several vibrating frequencies of the measuring tube. The evolution of the axial velocity, a distortion of the axial velocity profiles, a secondary flow in the measuring tube, and a twisting moment acting on the tubes wall were observed. Values of the twisting moment that acts around the centre of the tubes length were used to evaluate the performance of the flowmeter at different mass flow rates and various dimensions of the measuring tube.
