Solid particle deposition in ship piping significantly affects the lifespan of the pipes and the normal operation of the vessel. This paper utilizes Ansys-Fluent fluid dynamics software to simulate and analyze the deposition patterns of solid particles inside a 90° elbow, investigating the effects of different bending ratios, flow velocities, temperatures, and various particle diameters on the deposition rate of solid particles. The results indicate that with the increase of elbow ratio, temperature, and particle diameter, the deposition rate of solid particles gradually increases; conversely, with the rise in inlet flow velocity, the deposition rate of solid particles gradually decreases, which exacerbates the impact of elbow ratio on the deposition rate. The deposition rate is most significantly influenced by flow velocity, followed by particle diameter, while temperature has a relatively minor effect. This study can be applied to reduce the incidence of pipeline blockage and provide a theoretical basis for the design of oil flow elbows.
