Abstract

Numerical simulations (using finite volume method) of the flow of a viscous fluid through a measuring tube were performed to identify the effects of different inlet-flow conditions on the performance of a straight, slendertube, Coriolis flowmeter. The magnitudes of the antisymmetric fluid forces and the twisting moments acting on the measuring tube were compared with results from a onedimensional fluid-flow model. Simulations were made for some hypothetical inlet-velocity profiles that represent extreme cases of various flowmeters’ installation positions and flow regimes in a pipeline. No significant effects of the modelled inlet-velocity profiles on the performance of the flowmeter were observed.
