Enhancing Dynamic Response of Cantilevered Rectangular Prism Using a Splitter Plate as a Passive Turbulence Control in Water Tunnel

The effects of splitter plate as a passive turbulence control on the transverse vibration characteristics cantilevered rectangular prism with different finite length (aspect ratio L/H) and depth ratios (side D/H 0.2 0.5) was investigated in water tunnel. A installed behind small gap sufficient to prevent vortex shedding intrusion. It enhances response amplitude ascended linearly respect non-dimensional velocity. In case prisms critical points, interferences signal spectra for period displacement vanished, yielding uniform waveform amplitude. Inserting improves increment rate dynamic test models. brief numerical calculation performed find quantities flow features around plain detached plate. alteration wake is found by diminishing unsymmetrical vortices reduce entrainment at trailing edge. essential findings are base pressure improvement, reducing drag force, vanishing sharp peaks FFT spectra.
