Sloshing assessment of LNG cargo tanks is expected to satisfy the required structural strength of insulation components. It is difficult to estimate the sloshing pressure and structural response of cargo containment in real size because of the uncertainty of intensive computation time as well as the complexity of sloshing motion. In this study, several procedural components are suggested to meet the endurable strength of LNG CCS during the design of LNG cargo containment. The measured sloshing impacts from small scale model test are treated by individual impacts. Thereafter, static and transient structural response of LNG CCS is sequentially performed in order to evaluate the structural strength. The structural response is also calculated in time series through convolution method considering the history of pressure. It is used to investigate the structural response induced by the history of impacts. Finally, an idealized fluid structure interaction on the localized insulation panel is investigated in order to evaluate the structural strength in actual scale.

Submarine pipelines are described as the lifeblood of offshore oil and it is crucial to ensure the seismic safety of the submarine pipelines. Based on the fluid-structure interaction numerical analysis method and by using finite element software ADINA, the analysis models of the free long-span submarine flexible pipelines under earthquakes were established. By employing dynamic time-history method, the influences of fluid-structure interaction on the seismic response of the submarine pipelines were researched. The results showed that the peak normal stress and the peak displacement of submarine pipelines’ mid-span considering the influences of the fluid-structure interaction are greater than those without considering the influences, and the influences of the fluid-structure interaction on the seismic response of the submarine pipelines will increase with the increase of the submarine pipelines‘ diameter.

Liquid Storage Tank

To large liquid storage tank, based on the potential flow theory, considering fluid-structure interaction, the potential-based elements and the shell elements are used to simulate the liquid and the tank, respectively. Using the displacement-velocity potential finite element method formulas, the seismic response analysis method of the liquid storage tank is obtained, and is implemented based on the ADINA program. Some useful conclusions of the tanks under the earthquake loadings are obtained through two examples, which provide the reference for the seismic design theory and the seismic performance, and provide the analysis approach for the damage behavior and loss assessment of liquid storage tank.

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.

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.

Inherent Frequency

For the aviation bending pipe, the fluid-structure interaction 14-equation model is established, and the Laplace transform is used to solve the problem in the frequency domain. For the pipeline with a single elbow, the influence of bending parameters on the frequency response of the pipeline in the frequency domain is analyzed by using the 14-equation. At the same time, for pipelines containing two elbows, we analyze the influence of bending parameters on the natural frequency of the pipeline in different spans. In the end, the accuracy of the simulation is verified by the modal knocking test. Through the above analysis, we reach the following conclusion:the bending angle of the pipeline is greatly influenced by inherent characteristics, the smaller the bending angle, the higher the pipeline’s inherent frequency domain. However, the effect of bending radius will cause the change in length. Usually, the increase of bending radius leads to pipe length increasing, resulting in its inherent frequency decreasing.
