Engineers and environmentalists are pursuing the utilization of renewable energy in lieu of ever the increasing demands for electricity. Our generation has inherited the charge for finding a solution to society's growing needs. Capturing wind energy was first conceptualized in 1888 by Charles. F. Brush, and has evolved into large scale wind turbines and generators known today. However, a small scale system for exploiting wind energy has eluded mass production, when it could realistically be implemented into our everyday lives. Through our daily tasks, society loses kinetic energy to the environment; a small scale wind turbine will streamline energy efficiency from a renewable source. Our goal is to design a propeller that will suit an aesthetic residential sized wind turbine that will perform well in a non-commercial environment and be easy to expand to a whole system.

“…Suatu teknologi turbin angin untuk pembangkit tenaga listrik yang sudah dikenal yaitu HAWT (Horizontal Axis Wind Turbin) dan VAWT (Vertical Axis Wind Turbin) [3]. Kelebihan dari turbin angin sumbu vertikal dibandingkan dengan yang sumbu horizontal adalah memiliki sumbu rotasi bertepatan dengan arah angin serta kesederhanaan rancangan sudu-sudu VAWT terutama memiliki bagian simetris dengan chord konstan [4].…”

IntisariTelah dilakukan penelitian dengan menggunakan generator ceiling fan 12 W, dengan jumlah gear 35 dan 60 serta cyclone ventilator dengan jumlah gear 95. Pada kecepatan angin yang sama kecepatan poros generator pada pasangan gear 95/35 lebih besar dibandingkan dengan pasangan gear 95/60. Tegangan keluaran generator untuk pasangan gear 95/35 lebih besar dibandingkan pasangan gear 95/60. Pada pasangan gear 95/35 daya listrik yang dihasilkan generator sebesar 2,0 mW pada kecepatan angin 4,0 m/s dan kecepatan poros 40,2 rpm. AbstractThe research has been conducted using the generator ceiling fan 12 W, the number of gear are 35 and 60 as well as the number of gear cyclone ventilator is 95. At the same wind speed at the generator shaft speed gear pair 95/35 is greater than that 95/60. The output voltage generator for gear pair 95/35 is larger than gear pair 95/60. In the gear pair 95/35 generator power output of 2.0 mW at a wind speed is 4.0 m/s and spindle speed is 40.2 rpm .KATA KUNCI: cyclone ventilator, daya listrik, kecepatan poros, generator I. PENDAHULUANAkhir-akhir ini perhatian pada fenomena penggunaan energi terbarukan khususnya energi angin meningkat dengan cepat. Hal ini disebabkan semakin langkanya keberadaan sumber daya energi tak terbarukan seperti minyak, gas bumi, batu bara. Oleh karena itu perlu adanya reformasi penggunaan energi di berbagai bidang kegiatan yang akan mendorong penggunaan teknologi baru [1]. Salah satu alternatif dari energi terbarukan adalah energi angin. Energi ini mudah diperoleh dan mudah proses produksinya. Energi angin telah banyak digunakan di berbagai bidang seperti pembangkit listrik, tenaga gerak pompa air [2].

“…Therefore, azimuthal changes in blade aerodynamics are unavoidable, resulting in regular time-periodic motion but also in complex flow phenomena such as stalled flows, vortex shedding and blade-vortex interactions (see [1] and references therein). The interested reader is referred to [2][3][4] for vertical axis turbines to generate wind power and to [5] for their use in urban environments.…”

Abstract:We develop a reduced order model to represent the complex flow behaviour around vertical axis wind turbines. First, we simulate vertical axis turbines using an accurate high order discontinuous Galerkin-Fourier Navier-Stokes Large Eddy Simulation solver with sliding meshes and extract flow snapshots in time. Subsequently, we construct a reduced order model based on a high order dynamic mode decomposition approach that selects modes based on flow frequency. We show that only a few modes are necessary to reconstruct the flow behaviour of the original simulation, even for blades rotating in turbulent regimes. Furthermore, we prove that an accurate reduced order model can be constructed using snapshots that do not sample one entire turbine rotation (but only a fraction of it), which reduces the cost of generating the reduced order model. Additionally, we compare the reduced order model based on the high order Navier-Stokes solver to fast 2D simulations (using a Reynolds Averaged Navier-Stokes turbulent model) to illustrate the good performance of the proposed methodology.
