| Description | Journal: Journal of Physics: Conference Series An underwater valve at 3000 meters underwater was chosen as the research object, aiming at obtaining the force characteristics of the underwater valve under high pressure and large temperature difference in the deep sea. The principle of fluid-solid-thermal three-field coupling was analyzed by using Fluent and ANSYS Workbench. Through numerical simulation, the fluid temperature distribution, the stress and deformation of the valve were obtained, and the valve was loaded. The influence of pressure and temperature on the performance of underwater valve was discussed. The results show that the fluid medium inside and outside the valve exchanged heat due to the large temperature difference, and vortexes were generated at the bottom of the valve seat, and the fluid pressure energy was converted into heat energy. The force of thermal stress generated by heat exchange on the valve body was greater than the equivalent stress generated by thermal-mechanical load. |
