Abstract:
Facing an increasing energy demand, Pakistan seeks sustainable solutions for its future, with wind energy holding significant potential. As non-renewable resources run out faster than they can be replaced, it is crucial to produce electricity from renewable energy sources including hydro, solar, and wind power. As of 2023, wind energy contributes approximately 6.8% of Pakistan’s total electricity generation. The total installed wind power capacity in Pakistan is around 1,845 MW, distributed across 36 operational wind projects.
Research is conducted to identify novel and inventive techniques that can function in the best wind circumstances, occupy less space by reducing the wake impact, and provide a high-quality result. One such technological advancement is the vortex bladeless wind turbine, which offers a silent, secure, easy-to-use, and effective substitute for traditional bladed wind turbines. This method uses the phenomenon of aeroelastic resonance to harvest wind energy.
A variety of mast designs were investigated by Computational Fluid Dynamics in order to investigate the possibility of greatly boosting vortex formation. Also, fluctuations in lock-in regions posed a problem due to the wind velocity's intrinsic non-linearity. To address these issues, a thorough redesign of the mast’s shape was carried out, along with the addition of a tuning mechanism that will allow for real-time modifications to the structural frequency. Previous research into the tuning system enhances its potential.
