| Zusammenfassung: | Monitoring fluid properties such as viscosity and density is crucial in many industrial processes. Sensors based on mechanical resonators allow monitoring the viscosity online, which enables a fast measurement times in order to maintain process quality and stability. To develop these sensors, accurate models are needed to optimize design and to gain a better understanding of their functioning. In a previous study, a tubular sensor has been investigated. It consists of a thin-walled tube which is excited in torsional vibrations. Experiments have been conducted and compared with a steady state model of the fluid-solid interactions that determine the behavior of the sensor. These agreed well with measured characteristics of the sensor ta low viscosities, but showed a significant deviation at high viscosities. It is not clear whether this was due to modal distortion or to temporal effects. This study investigates the cause of these deviations at high viscosities by means of numerical simulations. This more detailed model accounts for temporal and well as fluid-structure interactions. Simulations are conducted in LS-DYNA and MATLAB to model the fluid-structure interaction to determine the impact of the fluid on the torsional mode as well as to include temporal effects. |
