The Finite Element Model

Coriolis mass flowmeter (CMF) is widely used in the industrial field. In mass flow measurement, there are many impurities in measured fluids that will adhere to the inner wall of the vibrating tube of CMF. The vibration characteristics of CMF would change due to the structural change, i.e., wall clung state, which will generate the wall clung state fault. In this paper, aiming at the wall clung state fault of CMF, the finite element model of CMF is established based on ANSYS. The velocity distribution of fluid in the vibrating tube of CMF is analyzed, considering the fluid–structure interaction. The location of the wall clung state in a vibrating tube is determined. Then, the fault model is established. The mechanism of the vibration transmission characteristics outwards of CMF caused by the wall clung state is analyzed by harmonic response analysis. Finally, the failure mode of CMF is investigated.

Based on the basic principle of fluid-structure interaction, this paper make a finite element analysis of seismic on upper water tank of HPR1000 outer containment by CEL method in ABAQUS software. Firstly, structure is simulated the by Lagrange grid and the water in upper water tank by Eulerian grid; secondly, coupling contact between water and structure is defined; finally, the calculation results are got by running an explicit dynamic solver to makes a time history analysis of fluid-structure interaction finite element model under the seismic, and the results will be used in the structure design of outer containment and upper water tank.

Transfer Method

The data transfer method for fluid structure interaction analysis using compactly supported radial based function (CRBF-FSI) is studied. It builds transfer matrix for data exchange and makes fluid and structure mesh use different shape and density unrestrictedly. Example of data exchange on 3D interface is studied. The efficient and the accurate of CRBF-FSI method are analyzed and also the influence of different compactly-supported radius is studied. The results show that CRBF-FSI method is suitable for FSI data transfer on complicated interface if compactly-supported radius is properly chosen. It has a bright future in practical use such as wind-induced response analysis in Wind Engineering.

Sudden Load

Coupled vibration of water and stop log gate in the layered water intake structure will occur under the condition of the sudden load changes. A fluid-structure interaction (FSI) finite element model of the layered water intake structure of a hydropower station was established by using the finite element software ADINA to simulate the process of power on and off and the FSI phenomena of stop log gate during each process, and also verify the security of the scheme. The results show that fluid-structure interaction has a significant impact on the running of the layered water intake.
