Vortex Bladeless Wind Turbines for Airport Runway Energy Generation: Conceptual and Economic Feasibility Studies
摘要
The global demand for sustainable energy is growing rapidly, especially in the aviation sector. The target of this project is to design an environmentally friendly vortex bladeless wind turbine (VBWT) to be applied at the airport runaway. The project largely centered on the extensive conception of the vortex technology, energy endurance, and the vortex bladeless turbine design using computational fluid dynamics simulations (CFD) of viscous shear–stress transport SST k-ω turbulence model (ANSYS FLUENT). Vortex-induced vibration (VIV) is the result of the classical Kármán vortices generated by alternating vortex formation due to the instability of the weakening boundary layers by adverse pressure gradient. The oscillatory flow phenomenon can typically be seen in the flow passing through a cylindrical or bluff-body-shaped object. The fluctuation depends on the unsteady lift and drag forces generated and the effects become greater for free-end three-dimensional flexible cylinders. This mechanical oscillation dynamics can be enhanced via resonance and if it could be harnessed appropriately, would be converted into useful energy for airport fundamental operations.
