Abstract

The basic problem of appropriate wind energy technology is how to design wind turbines from materials that are easily available on the market, one solution is PVC pipe as the blade material. For this reason, it is necessary to analyze the working stress that occurs in the blade construction, so that the PVC pipe propeller wind turbine is safe when applied in society. The purpose of this study was to determine the effect of wind speed and tip elbow width on working stress. The simulation test method uses SolidWorks Flow Simulation Software and then the results are exported to Static Simulation to determine the strength of the material. Simulation tests were carried out with wind loads on PVC pipe propellers with wind speeds of 5 m/s, 6 m/s, and 7 m/s and elbow tip widths of 100 mm, 110 mm, and 130 mm. The results of the maximum stress value in the wind turbine simulation test with the addition of an elbow tip were obtained at a wind speed of 7 m/s and an elbow tip width of 130 mm

Abstract

The dependencies on fossil energy as a basic energy source has many negative impacts, therefore alternative energy is needed to overcome the problem, one of which is the alternative green energy wind turbines. However, wind turbines in Indonesia are difficult to implement because the wind speed in Indonesia is low, which is around 4-8 m/s, therefore it is necessary to do research to improve the ability of wind turbines applied in Indonesia. The analysis method using the 6 DoF CFD method and the experimental carried out using the wind tunnel. The blade used in this study is a custom combination airfoil with the chord lengths of 0.1 m, 0.15 m and 0.2 m. The results shows that, at wind speed of 8 m/s the blade with a chord length of 0.2 m has the greatest pressure of 47 Pa and rotational speed per minute of 76.1 rpm, this variation can be applied to low rpm generators. Whereas blades with a chord length of 0.1 m and a twist angle of 15o have a pressure of 47 Pa, and rotational speed of 97.24 rpm per minute, this variation can be applied to high rpm generators.

Abstract

At this time the power plant still uses a lot of coal fuel, so it is necessary to look for alternative energy, one of which is wind energy. Wind turbines are devices that can convert kinetic energy in the wind into mechanical energy which is then converted into electrical energy through a generator. The analysis method in this research uses Computational Fluid Dynamics (CFD), Qblade, and experimental validation testing using a wind tunnel. The simulated airfoil types consist of 3 types, namely, NACA 4412, NACA 4415, and FX-60 100 (126). The simulation results show that, the most optimal airfoil is NACA 4412 with an angle of attack of 25° and a wind speed of 8 m/s can produce a torque of 3.55503 Nm, a pressure of 45 Pa, a tangential velocity of 55.495 m/s, and a rotational speed of 529. 94 rpm, while the smallest simulation results are on the FX-60 100 (126) airfoil with an angle of attack of 15° and the same wind speed of 8m/s can produce a torque of 1.60390 Nm, a pressure of 40 Pa, a tangential velocity of 9.06592 m/s, and a rotational speed of 108.2164 rpm. The results of experimental testing of wind turbines where the wind turbine used uses the geometry of NACA 4412 show that an angle of attack of 25 ° and a wind speed of 8m / s produces a large electrical power and rpm with a value of 7.98 Watt and 482.2 rpm respectively

Abstract

The selection of the appropriate blade shape requires optimization in order to be applied to the relatively low wind conditions in Indonesia. This study proposed a new approach of wind turbine blades design by utilizing the combination of NACA 4415 and FX 60. The effect of twist angle and the chord length carried out in this study to better understanding the blades characteristics. The 6 DoF analysis can be used to determines the theoretical mechanical power of the wind turbine blades. The blade twist geometry analyzed in this study is 15, 20, and 25 degree. From the simulation results, the highest mechanical power was obtained on blades with a twist angle of 5 degrees and a chord length of 0.15m with an average value of 39.95 W. The simulation results show that, at a speed of 8 m/s the blade with a chord length of 0.2 m and a twist angle of 5o has the greatest torque of 5.16579 Nm, with a rotational speed of 76.0668 rpm per minute, this combination can be applied to a low rpm generator A twist angle can improve torque distribution along the blade, but a twist angle that is too sharp can reduce lift and increase drag. It was found that a wider chord length tends to produce lower rotation in the wind turbine. This is caused by the increased surface area on the turbine blade with a longer chord length, which results in an increase in the torque required to rotate the blade at a given speed.

Abstract

The unknown torsional strength due to the inconsistency of the angles and dimensions of the square cross-section of AISI 1020 steel specimens in the torsion test is the problem encountered. The research method included: preparation of square AISI 1020 steel specimens measuring 6 mm x 6 mm x 160 mm, measurement of 2 diagonal angles of the cross section of the specimen and dimensions of the cross section at 5 observation points along the specimen receiving torsion loads, torsion testing of specimens, analysis of torsion test results data, and drawing conclusions. The results of the study affect the angle and dimensions of the specimen cross-section on the torsional strength of the AISI 1020 steel square shaft which has a greater value at the angles of 89o and 91o than 90o which with an angle of 89o at dimensions of 5.96 mm x 5.96 mm has a torsional strength of 412 MPa, while at an angle of 90o with dimensions of 5.96 mm x 5.96 mm it has a torsional strength of 359 MPa, and for an angle of 91o in dimensions of 5.95 mm x 5.95 mm has a torsional strength of 402 MPa. The average torsional strength is achieved in the range of 351 to 397 MPa, at an angle of 89o the torsional strength increases by 46 MPa or around 13.1 %, and at an angle of 91o the torsional strength increases by 43 MPa or around 12.3%.
