Fluid-Structure Interaction (FSI) Simulations on the Sensitivity of Coriolis Flow Meter Under Low Reynolds Number Flows

Vivek Kumar, Martin Anklin, Benjamin Schwenter

Abstract

In process industries Coriolis mass flow meters (CMFs) are widely employed for measuring mass flow rates. Quite often especially in oil and gas (O&G) industry, owing to fluids with high viscosities, flow measurements may lie in low Reynolds number regions. At low Reynolds numbers (Re), a CMF reading may deviate under the influence of fluid-dynamic forces. With the help of extensive Fluid-Structure- Interaction simulations (FSI), a detailed insight into physical mechanisms leading to this deviation is provided. The main finding is that this deviation is a function of the Reynolds number and the effect can be explained by a periodic shear mechanism which interacts with the oscillatory Coriolis force. Experimental results with and without the correction are shown and compared with corresponding numerical results.
