Thermal?Fluid?Structure Coupling Analysis of Flexible Corrugated Cryogenic Hose
文献摘要：
This work presents a numerical investigation of the thermal–fluid–structure coupling behavior of the liquid natural gas (LNG) transported in the flexible corrugated cryogenic hose. A three-dimensional model of the corrugated hose structure composed of multiple layers of different materials is established and coupled with turbulent LNG flow and heat transfer models in the commercial software ANSYS Workbench. The flow transport behavior, heat transfer across the hose layers, and structural response caused by the flow are analyzed. Parametric studies are performed to evaluate the impacts of inlet flow rate and thermal conductivity of insulation material on the temperature and structural stress of the corrugated hose. The study found that, compared with a regular operating condition, higher inlet flow velocities not only suppress the heat gain of the LNG but also lower the flow-induced structural stress. The insulation layer exhibits excellent performance in maintaining the temperature at the fluid–structure interface, showing little temperature change with respect to material thermal conductivity and ambient temperature. The simulation results may contribute to the research and design of the flexible corrugated cryogenic hoses and provide guidance for safer and more efficient field operations.
