Mathematical modeling of turbulent flow in vicinity of a prism installed on a plate taking into account aeroelastic effects

摘要

The paper presents the results of numerical modeling of oscillations of an elastic rod of rectangular cross section set normal to external flow and fixed rigidly to a plate. The simulations are performed in ANSYS using the 2-way FSI technology [1, 2]. The modal, hydrodynamic and coupled calculations have been performed. The excitation of aeroelastic vortex induced rod vibrations is simulated. The influence of the turbulence model choice is demonstrated on the vortex shedding frequency that can significantly affect the vibration excitation process.
