Abstract

The National Energy General Plan policy is one of the government's focuses on controlling the use of renewable energy in line with the development of the need for energy use for the community, especially in the electricity sector. Electrical energy is energy that is very important for human needs, where every human being is very dependent on electricity for their daily needs. Currently, there is a crisis of fossil resources, so renewable energy can be developed. One renewable energy that is easy to develop is a wind turbine by utilizing the energy of the wind that blows. Indonesia has started to pay attention to increasing the efficiency of electricity generation, especially wind power. The type of turbine planned is the Darrieus type vertical axis wind turbine (VAWT) using a modified NACA Airfoil 2414 geometry with variations in wind speed. At a speed of 7,61 m/s from the test results obtained the power produced by the turbine is 20,78 watts with a voltage of 11,61 Volts and an electric current of 1,79 Amperes and at 354 rpm generator rotation. from the results obtained, the higher the wind speed, the higher the rotation produced by the turbine.

Abstract

The geometry of an airfoil plays a critical role in shaping an aircraft's performance, especially during maneuvering. This study emphasizes the necessity of conducting a comprehensive geometric analysis to better understand the effects of airfoil design. In pursuit of optimizing airfoil performance, we conducted extensive tests on NACA 2412 and 2415 series airfoil geometries using the ANSYS Fluent software. The tests employed Aluminum Alloy 1067 material and a wind speed of 300 m/s, encompassing a range of angle of attack variations from 0 to 180 degrees. The simulation results provided valuable insights into the velocity and pressure distributions surrounding the airfoil. Of particular interest, at an angle of 15 degrees, the NACA 2412 airfoil exhibited a maximum drag force of 69.670 N and a maximum lift force of 550.300 N. The corresponding drag and lift coefficients were 0,1516378 N and 1,1977364 N. For the NACA 2415 airfoil, the maximum drag and lift forces were 71.470 N and 564.500 N, respectively, with corresponding drag and lift coefficients of 0,1541963 N and 1,2179072 N.

Abstract

Analysis of the airfoil's shape on an airplane wing is essential because geometry can determine aerodynamic performance and the forces at work, such as lift and drag. In this research, two types of aluminum materials, namely Aluminum Alloy 7075 T6-SN and Aluminum Alloy 7050-T7451, will be tested to find out which one can produce the highest lifting force and drag force on NACA 0018 and 0024 as well as look at the pressure contour and speed Contour of each type of material using ANSYS Fluent software at a speed of 200 m/s. From the simulation and calculation results, it was obtained that the highest lift coefficient and drag coefficient on the NACA 0018 Airfoil were using Aluminum Alloy 7075-T6 SN material, namely 6.83 N and 6.89 N. Meanwhile, in the NACA 0024 Airfoil simulation, the highest lift coefficient and thrust coefficient were obtained. It also uses aluminum Alloy 7075-T6 SN, namely 3.23 N and 4.64 N.

Solar power plants continues to experience good development and even PLTS can be used to overcome environmental problems, so this research aims to utilize renewable energy as a driving force for waste processing machines by designing organic waste chopping and grinding equipment. The specified motor power is 2 HP or 1.5 kW with 275 rpm, so the number of panels required is 12 pieces which are converted into AC from DC by the inverter. Based on power and rotation, the torque calculation results obtained are 2760 kg cm, the shaft diameter is 18.86 mm, the belt type is type A with a top belt width of 12.5 mm and a thickness of 8 mm, and transverse pegs with a width of 8 mm, a thickness of 7 mm. and 40 mm long based on ISO 2292 (according to pulley hub thickness). Based on the calculations and transmission design, a waste processing tool was built and then tested. From the tests, it was found that the power produced by PLTS was 1.5583 kW at 2239 Lux light to chop up 2 kg of organic waste.

Abstract

During takeoff and approach to land, all aircraft move at low speed and high lift so that the wing is one of the main components of an airplane that has the basic function of being able to produce good aerodynamic performance characteristics so that objects can be lifted and maintain their position in the sky. In this study, an airfoil geometry with the NACA 0012 and NACA 4415 series was tested using ANSYS Fluent software at a speed of 200 m/s. To obtain maximum performance in this geometry, a variation of the angle of attack from 0° to 20°, was given so that the lift and drag force were obtained from each angle of attack. From the simulation and calculation results, the highest lift coefficient and drag coefficient in the NACA 0012 Airfoil simulation are at an angle of attack of 20°, is 0.5106 and 0.07829. Meanwhile, in the NACA 4415 Airfoil simulation, the highest lift coefficient is at an angle of attack of 20°, is 0.64623 and 0.08238.

Abstract

Wind energy for electricity generation presents a promising alternative to fossil fuels, driving the development of renewable energy technologies. Computational Fluid Dynamics (CFD) stands out as a powerful tool in this domain. This study focuses on optimizing the design of Gorlov turbines through a combination of CFD simulations and the Taguchi method. The research identifies four key factors influencing turbine performance: twist angle, chord length, number of blades, and aspect ratio. These factors are systematically varied using an orthogonal array, resulting in nine distinct blade configurations. Subsequently, simulations are conducted using ANSYS Fluent software under transient conditions at a wind speed of 5 m/s. Simulation results reveal that the maximum angular velocity achieved is 29.8187 deg/s, accompanied by a torque of 0.426 Nm, leading to a calculated maximum power output of 12.73 Watts. Furthermore, Taguchi analysis and ANOVA are employed to assess the significance of each factor. The analysis highlights the aspect ratio as the most influential factor, accounting for 99.7% of the observed variation. This study underscores the potential of CFD and the Taguchi method in optimizing wind turbine design for enhanced performance. The findings emphasize the critical role of the aspect ratio in determining turbine efficiency, paving the way for more efficient renewable energy generation.

Analisa geometri airfoil pada suatu sayap pesawat sangat diperlukan karena geometri dapat menentukan performa aerodinamika serta gaya-gaya yang bekerja, seperti gaya dorong dan gaya angkat. Dalam penelitian ini, suatu geometri airfoil dengan seri NACA 0008 dan NACA 0010 diuji menggunakan software ANSYS Fluent berbahan Aluminium Alloy 1067 pada kecepatan 200 m/s. Untuk mendapat performa yang maksimum pada geometri ini, diberi variasi sudut serang dari 00 sampai 300 sehingga diperoleh gaya angkat dan gaya dorong serta kontur tekanan dan kontur kecepatan dari masing-masing sudut serang. Dari hasil simulasi dan perhitungan diperoleh koefisien angkat dan koefisien dorong tertinggi pada simulasi Airfoil NACA 0008 adalah pada sudut serang 300 yaitu 3,96 N dan 2,24 N. sementara pada simulasi Airfoil NACA 0010 koefisien angkat tertinggi pada sudut serang 300 yaitu 3,69 N dan 2,06 N.

Abstract

Micro-Hydropower (MHP) is a renewable energy source that can be utilized to generate electricity on a small scale. This study aims to analyze the effect of water pressure variations on the performance of a laboratory-scale Pelton turbine and compare the performance of a single-nozzle and a double-nozzle system. The research method used was an experimental method with pressure variations of 2, 2.5, and 3 kg/cm² and electrical loads of 5–25 watts. Observed parameters included turbine rotation, voltage, current, output power, and system efficiency. Test results showed that increasing water pressure increased turbine output power and efficiency in both nozzle configurations. In the single-nozzle configuration, the maximum output power reached 15.19 W with a peak efficiency of 9.8% at a pressure of 3 kg/cm². Meanwhile, in the double-nozzle configuration, the maximum output power was 11.12 W with an efficiency of 7.2% at the same pressure. In general, the single-nozzle configuration performed better than the double-nozzle configuration in a laboratory-scale Pelton turbine system due to a more optimal water jet distribution and lower hydraulic losses.
