The purpose of this research is to protect copyright and the government's Venturi meter is a tool for measuring the mass flow rate or volume flow in a closed channel. The geometry and dimensions of the Venturi meter consist of various shapes, especially on the neck which is used as a barrier. The shape of the Venturi meter that is widely used varies, but basically has the same way of working, namely by measuring the pressure difference at two specified points. Dimensional changes between the slope and the neck of the venture can cause differences in pressure values. The two points set are the highest points for the pressure difference that occurs on the measuring instrument. Calculations only involve the equations of Energy, pressure and flow continuity. From the analysis of the change in the average pressure accurately occurred at a tap distance of L = 125 mm and an average pressure at 674.6 Pa for flow rates of 0.2 and 0.5 kg/s with fillet sizes between 45 – 50 mm.

Preheater is one form of heat exchanger which serves to heat the working fluid to be fed to the next heating arrangement. Generally the source of thermal energy used is exhaust gas that still has a high temperature obtained from the previous heating system. The amount of heat flow rate given by the hot gas to the water in the pipe is able to provide hot water supply. Construction planning preheater made such use LMTD approach and effectiveness as well as the integrated CFD simulation on Anys15.4, so it can be seen that the performance of the tool. The final results of modeling provide flow and temperature distribution occurs in the heat exchanger. The capitalization use 3D steady flow by choosing K-ℇ turbulence modeling standards as well as to enable the energy equation. Data inputs are incorporated into the application is the result of measurements and calculations done before

Abstract The wind speed in Indonesia is only around 3 meters/s to 12 meters/s, it is quite difficult to generate electricity on a large scale, it also makes the utilization of wind energy still very low. However, the wind potential in Indonesia is available almost all year round, so there is a possibility of developing technology to utilize this energy with some of the limitations mentioned above. Modifications of windmills need to be carried out which are adapted to low wind speed conditions to be able to produce optimal electrical energy. Therefore, a HAWT (Horizontal Axis Wind Turbine) design was made using a NACA airfoil that has a high Cl/Cd value to produce 500 W of power at wind speeds of 1 meter/s – 12 meters/s. The research was conducted in 3 stages. The first step is the calculation to determine the radius, chord, and twist of the blade. The two initial design stages of the blade are carried out in a simulation using QBlade software to determine the NACA airfoil used and determine the performance coefficient and the resulting power. The three stages of blade design use Solidworks software which produces a 3D blade design. The design results produce a HAWT blade with a taperless NACA 2412 airfoil with a blade radius of 0.75 m, 0.12 m chord width, and a twist angle of 5.42°-15.46°. At a wind speed of 10 m/s, the blades have a maximum Cp of 49%, maximum power of 923 W at an angular speed of 1000 rpm, and a minimum power of 90 W at an angular speed of 200 rpm. The average power generated is 567W.

Wind energy is one of the most popular renewable energy alternatives. In the use of wind energy, of course, tools and technology are needed to process and process the energy conversion process. One technology that can be applied is wind turbines. Wind turbines are able to convert the kinetic energy of the wind into mechanical motion which is used to drive a generator that converts mechanical motion into electrical energy. From this case, the part of the windmill that plays a significant role in the process of converting wind energy is the blade. Therefore it is necessary to design a good blade based on field research so as to create a blade design that is able to work optimally according to the characteristics of the blade installation site. From the problems above, the authors are motivated to explore the process of making blades, and the process of making blades on the Wind Turbine is carried out with the Taper type with Airfoil NACA 6510 which consists of designing, selecting materials, machining processes. The material used for the process of making blades on the Taper Wind Turbing with Airfoil NACA 6510 is mahogany wood. The results of the process of making blades on a Taper Wind Turbine with Airfoil NACA 6510 obtained a radius of 0.8 m, linear chord from 0.113 – 0.70 m, torsion angle 12,580 – 5,580

The shaft is the most important part of a transmission system that functions to continue rotation and mechanical power. In general, shafts are made in stages according to the conditions required. For each multilevel shaft section, radius fillets are always used. The purpose of this fillet is to reduce stress concentrations that occur due to changes in shaft diameter or other geometry. The constraints that arise are how large the size of the fillet must be used and what if the load that occurs is a combination of bending and twisting. From the results of research using the Ansys 14.5 application, it shows that a larger fillet size can distribute the maximum stress that occurs in that area. At a bending load of 250 N mm and a torsional load of 400 N mm with a fillet of 0.2 the maximum stress that occurs is 0.404 N/mm2. Whereas in fillet 0.12 the stress that occurs is 0.589 N/mm2.

Venturi meter is a measuring tool that functions to measure the mass flow rate of fluid flowing in a channel by applying a pressure difference. The pressure difference is generated by the narrowing of the channel from the inlet to the outlet. The difference in the dimensions of the inlet and outlet affect the Coeffeesin discharge Cd value of the measuring instrument. The value of the Cd range from existing standards ranges from 0.90 to 0.97 depending on the Reynolds number experienced by the fluid. From the results of experiments carried out through CFD simulations with several variable ratios of the inlet and outlet dimensions of 0.25, 0.5 and 0.75 with variations in speed of 0.5, 1 and 1.5 m/s. From these results an ideal Cd value of 0.992 was obtained. With the resulting ratio of 0.5.
