description: The topic of the final qualifying work: "Numerical study of a three-dimensional bottom flow for a model of well-streamlined bridge supports." This work is devoted to the study of the effect on the bottom flow of water of the distance between the models of well-streamlined bridge supports and the angle at which the fluid flows onto the supports (angle of attack). The calculations were carried out using the commercial code ANSYS FLUENT 2019 R3. Within the framework of the work, the following tasks were solved: 1. Comparison of the flow structure for the case when half of the profile is modeled, and for the case that reproduces the full profile; 2. Investigation of the influence of the distance between two model supports of the bridge on the flow; 3. Investigation of the influence of the angle at which the flow flows onto the obstacle, on the flow structure near the bridge supports; 4. Joint study of the influence of the distance between the bridge supports and the angle of attack on the flow structure, as well as on the drag coefficient. In this work, meshes were implemented for the full profile of a cylinder equipped with a fairing, followed by a comparison of a similar solution for half of the profile. Analysis of the influence of the distance between supports on the flow structure. The study of the influence of the angle of attack on the flow has been carried out. Assessment of the combined effect of the angle of attack and distance on the flow, as well as comparison of the drag coefficient value at different angles of attack and different geometries.
