“…4.1 Geometry and topology of VAW The three-blade configuration is on the assumption that the three blades are more stable in comparison to the two or four-blade configuration(see Fig: 1) [13]., furthermore research is conducted on the aspect on a vertical axis wind turbine, that a higher aspect ratio has a lower power coefficient and vice versa [14] [15].…”

The effects of sound pressure level at two observation positions of a fixed and varied blade pitch angle at Low-Mach unsteady incompressible Reynolds-Average Navier-Stokes flow approach, on an H-rotor Vertical Axis Wind Turbine. The objective of the study is to compare the noise dissipation and output power/energy of the airfoil blades design of the vertical axis wind turbine in residential zones. The Ffowcs Williams-Hawkings (FHWH) techniques were applied to validate the output noise and vortex shedding of the different angles of attacks (AoA). The study postulated that the time history of the calculated sound pressure level at two observers positions: the aeroacoustic, blade vortex interaction noise, flow separations, dynamic stall experience from varied angled of attacks are found to produces less noise and vortex shedding compared to the fixed angle of attack.

At present business competition in Indonesia is getting tougher, including business competition in the field of wig making. PT Mono Jaya is one of the companies engaged in the production of wigs that are in Kroya, Cilacap district, Central Java. To increase competitiveness against its competitors, companies must be able to create new innovations and use information systems that are in accordance with the needs of the company as a support to improve performance, increase competitiveness against its competitors, and realize the company's goals. But to get an information system that fits the needs of the company, it requires an information system strategic planning. This study uses the Ward And Peppard method, the tools used are SWOT analysis, Value Chain analysis, McFarlan Strategic Grid analysis, Five Force Porter Model analysis, Critical Success Factor (CSF) analysis, and Balaced ScoreCard (BSC) analysis. The final results of this study are in the form of information system portfolio recommendations that are needed by PT Mono Jaya to improve the competitiveness of the company

“…The chosen airfoil profile along with the conventional NACA0018 has been described below. To generate higher torque at low wind speed more number of blades is preferred [15]. In other words, the increased solidity will bolster the low wind speed performance.…”
