Vortex induced vibrations
Szarka, Beáta ; Pluskal, Tomáš (oponent) ; Rudolf, Pavel (vedoucí práce)
This thesis deals with vortex-induced vibrations on different bluff body cross-sections. The theoretical part provides an overview of current energy production trends and introduces a hydrokinetic energy harvester, the VIVACE converter. The main principle of the system is a bluff body immersed in fluid flow undergoing vortex shedding formulating Kármán vortex street. The practical part deals with the evaluation of different profiles by forces acting on the bodies, frequency, and Strouhal number using 2D CFD simulations. The output of the investigation is the selection of the ideal cross-section shape of a cylinder for a VIVACE converter.
