Ejectors are common devices on board liquid carrier vessels and meet on both cargo and ballast tanks. The “in-line” ejector presented in this paper is an original model that was designed with NX Siemens, using information and technical data from a worldwide supplier of high quality marine products. This paper presents a static analysis of fluid’ influence which passing through an ejector on its metal structure using Ansys. From a previous work we took into account the data obtained with CFD (computer fluid dynamic) analysis. The pressure and fluid temperature fields were imported and applied to the meshed ejector model with finite elements, obtaining data on deformations and equivalent stresses and elastic strain.
