Abstract

Centrifugal pump at the graving dock experienced cavitation. It caused noise and a damage to its impeller as vapor bubbles appeared around it. This problem caused the centrifugal pump’s power decreased. The research method to solve it is collecting, calculating, and analyzing data. The calculations analyzed are the calculation of velocity, friction factor, head losses, pump head, NPSHA and NPSHR values. If NPSHA value is less than NPSHR, the pump is cavitated and modification to the piping system is needed so that the cavitation problem can be overcomed. The NPSHA calculation result is 4.77 m while the NPSHR is 6 m so that the it can be concluded that the pump experienced cavitation. Based on these calculations, modification of its centrifugal pump piping system is required. The pump which was originally had a suction pipe length of 6 meters was shortened to 5 meters. The pump position was lowered so that the suction pipe could reach the lowest water level at the graving dock. The pipe diameter of 0.3 meters was enlarged to 0.4 meters. After modification, the NPSHA value exceeds the NPSHR by 0.7 meters so that the centrifugal pump will be safe from cavitation.

Abstract

The previous Savonius wind turbine studies have proved that overlap modifications to conventional blades can improve turbine performance. With these conventional blades, the performance is less optimum because the drag force generated by turbine's rotation is still high. Based on this condition, this experiment is conducted by modifying Savonius wind turbine with overlap blades using Myring equation n = 1. Its blade profile is made half-elliptical to reduce drag force. Diameter and height of the turbine are 400 mm with 0.3 overlap ratio. The ratio of cylinder diameter (ds/D) is 0.4, and the ratio of cylinder center distance (S/d) is 1.7. Experiments are conducted by varying stagger angles of circular cylinder in front of returning blade i.e 45°, 50°, 55°, and 60°. Its wind speed variations are 5 m/s, 6 m/s, and 7 m/s. The final results show that the best performance improvement of the turbine occurs at 60° stagger angle and 6 m/s wind speed. The increase in torque coefficient is 4.95% and power coefficient is 20.16% to overlap Savonius wind turbine with myring n = 1 with no circular cylinder

Abstract

Savonius wind turbines are widely used for wind energy utilization eventhough theirperformance is considered lower than other types of turbines. In 3 previous studies, additionaldisturbance cylinder in front of returning blade and additional fin on blade could improve the turbineperformance but the increase was not optimum. Based on these problems, this experimental study usedone additional fin type myring n = 1 on the blade. Circular cylinders have a distance ratio of 340 mm,with various airspeed of 7 m/s, 6 m/s, 5 m/s, and various cylinder angles of 45°, 50°, 55°, 60°. Theexperiment was performed 12 times to determine the effect to coefficient of power (Cp) and coefficientof torque (Ct). The turbine best performance is obtained at a cylinder angle of 60° and a wind speed of6 m/s. The results are 0.394 for coefficient of power (Cp) and 0.688

Abstract

Previous experiment has been carried out on Savonius wind turbine with additionaloverlap ratio and variation of circular cylinder stagger angle to improve its performance.However, the experiment didn’t show flow visualization around the turbine. Therefore,numerical simulation using Computational Fluid Dynamics (CFD) method must be carried outto validate the experiment result and obtain the best performance and flow visualization ofoverlap Savonius wind turbine. The turbine simulated has an overlap ratio of 0,3. Then, thecircular cylinder is placed in front of returning blade with a distance ratio (S/d) 1.7 andvarious stagger angle of 45 ?, 50 ?, 55 ? and 60 ?. The flow velocity used is 5 m/s. Turbulencemodel used in this simulation is k-epsilon realizable with transient pressure based. The finalresult is overlap Savonius wind turbine with circular cylinder has increased its performance of31,56 % compared with overlap Savonius wind turbine without circular cylinder. The bestperformance occurs at 55 ? circular cylinder stagger angle in front of returning blade with0,4118 Coefficient of Power (Cp) value. The flow visualization shows that 55 ? circular cylinderstagger angle is able to create the most optimum nozzle effect.

Abstract

Sebagai industri yang memproduksi alat musik tiup seperti saxophone, flute, clarinet, recorder, dan pianica.. Dalam proses pembuatannya banyak proses yang dilalui seperti pengkilapan material logam, penghalusan permukaan material, soldering, dan lain sebagainya. Dalam proses tersebut tentu akan menghasilkan debu kotor dan tidak sehat. Dan bilamana kondisi partikulat debu melebihi nilai ambang batas akan menyebabkan gangguan kesehatan, ketidaknyamanan dalam bekerja, dan mengurangi aktivitas kerja. Proses perancangan sistem dust collector ini dimulai dari observasi lapangan, permodelan dust collector existing debgan software Ansys, perhitungan dust collector baru, perancangan dibantu oleh software CAD (Computer Aided Design) untuk pembuatan gambar serta analisis daya hisap menggunakan software ansys.

Abstract

The metal casting industry is an activity of processing molten metal material formed in a mould pattern to produce the desired product. Because the gas emissions released during metal smelting have an impact on the safety and health of workers, there is a decrease in air quality and a dust concentration of 1608.30 ?g/m3 is obtained. This value is above the threshold determined by the Decree of the Governor of Central Java no. 8 of 2011 which is 230 ?g/m3. In machining, the entire mould area, and induction furnace are areas that produce a lot of dust particulates. For this reason, it is necessary to design an air filtration system, namely a dust collector system. Dust collector works by sucking dust and air using a pump which is then filtered using a dust filter. The analysis process of this system design will use computational fluid dynamics method. With the analysis of the working system of the machine, it is expected that it will work optimally in air circulation in the metal smelting production building. Then a Cost Budget Plan will also be carried out, in order to estimate the amount of costs required in the installation of the design of the dust collector system. The calculation results in the simulation show that the best performance is in the layout design 2. The suction capacity in the layout design 2 is 13.57 m3/s. These results are not much different from manual calculations or hand calculations.
