Course objectives:
|
The subject is oriented on interactions among flow and bluff elastic bodies. Student will be aquanted with computationally and experimentally solved following problems of technical practise: Action of Karman vortices on flown round bodies. Galloping, responses of systems with one and two degrees of freedom. Nonstability of aero-hydrodynamically coupled system of bodies: tubes in bundle of heat-exchanger, blades of turbine and compressor, heat-fluid forces, stability analysis. Self-excited vibration generally, fluid coefficients of mass, stiffness and damping, possibilities of their numerical and experimental determination. Vibration caused by turbulence, examination of the body displacement spectrum from knowledge of the turbulent flow velocity spectrum.
