description: The subject of the graduate qualification work is Â«Implementation and testing of a coupled two-dimensional CFD and rigid body dynamics solver in SINF/Flag-S codeÂ». The given work is devoted to expanding SINF/Flag-S computational suite with a coupled CFD and rigid body dynamics solver based on moving grids method. Implemented methodology is used to simulate vortex-induced vibrations of a cylinder in the laminar flow regime. Cylinders of circular and elliptic cross-section are considered. Calculations for the case of forced rotation around the body's axis are carried out. As a result of the graduate qualification work, the option for joint integration of fluid and rigid body dynamics equations has been successfully implemented in SINF/Flag-S code. Simulation results for vortex-induced cylinder vibrations are compared with earlier works: numerical characteristics of established body position oscillations (amplitude, frequency) and phase difference between the lift force and transverse cylinder displacement are considered. For elliptic cylinders the effect of aspect ratio on body motion and fluid flow is studied. Influence of forced rotation is also analyzed.
