Numerical research of flow past a circular cylinder with a splitter at the subcritical Reynolds number region of 5 × 104—9 × 104 was researched based on Computational Fluid Dynamics (CFD) through solving twodimensional incompressible unsteady Reynolds-averaged Navier-Stokes (URANS) equations with the shear stress transport (SST) k-ω turbulence model. Three different grid resolutions were employed...
A novel bluff body wake energy harvester called Vortex Induced Piezoelectric Energy Converter (VIPEC) was proposed. The VIPEC consists of a circular cylinder, a pivoted beam and several piezoelectric patches. Computational Fluid Dynamic (CFD) simulation coupled fluid, structure and piezoelectric interaction was conducted to research the open circuit voltage and the output power at Reynolds number...
