Abstract

This paper describes dynamic modeling and model validation of a couple-tank control system which consist of a couple-tank, two motor-and-pumps, two electric-motor drivers, and two water-level sensors. Initially, dynamic modeling of the couple-tank was derived analytically. This derivation produced several parameters whose values were unknown. Experiments were then performed in order to obtain the values of those parameters. In addition to the couple-tank, other components were also modeled statically. Once all components of the couple-tank controlled system have been modeled, model validation of the whole system can then be performed.

Abstract

Pump as Turbine (PaT) tested from mixed flow pump type with 250 mm bore diameter, and impeller tip has a minimum modification by rounded the blade, which could improve the efficiency of 2% to 6%. The modification is done by rounded the impeller tip with 2 mm radius. Tested Pump as Turbine at 1000 rpm has an efficiency about 82% and 10 kW power output. The best power produced by 250 mm bore Pump as Turbine is 25 kW at the 75% efficiency. The 15 meters head may have the runaway speed of the Pump as Turbine on asymptotic level at 2500 rpm. The pump as turbine could utilized as Micro Hydro Power driver in the low cost, compare with Francis turbine design and development cost, which is mass production of the pumps and abundant at the market.

Abstract

This paper describes the motivation and design criteria for the development of a couple-tank control system which is intended to be used as a demonstration apparatus for a lecture course on Introduction to Control Systems. The work also demonstrates the performances of the controlled system in tracking various types of command inputs, Control strategies implemented to the system are On-Off control, Proportional control and Proportional-Integral control. Influences of dynamic interaction between channels on the performance degradation are also shown in this work. Except as a control system design example, this work is expected to be useful to mechanical engineering lecturers giving courses on Introduction to Control Systems, particularly to those in private universities.

Abstract

To overcome the difficulties in calibrating a hot wire anemometer the equation E2 = A+BU0.45, as the reference equation in making hot wire anemometer, was changed to U = (1/ B (E2-A))2.22 to produce linear calibration curve. To realize this idea then an electronic circuit was designed with IC AD 534 and AD 538 as the main components. IThe hot-wire anemometer was made based upon the above principles then used to measure velocity components of swirling flow, which has two components of velocity, i.e.: axial (normal) velocity and tangential velocity. In measurement of swirling flow the probe-X was used to measure axial velocity and tangential velocity simultaneously. Magnitude and direction of swirling flow were determined from those velocity components.

Abstract

This study aims to investigate the characteristic of a compact generator – hydro turbine system. The generator is of permanent magnet type and the turbine operates in a very low head. The integration of the two components is conducted in such a way that simplifies the construction of the conventional turbine generator. The method is by mounting the generator stator to the turbine casing and the permanent magnets are assembled in the perimeter of the turbine blade rotor. This simple construction is approached by making the stator from individual teeth and yoke. The permanent magnet generator (PMG) is designed to produce the nominal power of 300 Watt 50 Hz at 83 rpm of turbine shaft. All components of the integrated turbine- generator are totally immersed in the water stream. The stator has to be hermitic to avoid water entering the spool. Another issue investigated is the influence of the type of the stator inner casing material to the generator performance. The results show, the PVC material for inner casing has a good influence to the generator performance compared with the mild steel material.

Abstract

Profil airfoil merupakan salah satu faktor yang mempengaruhi kinerja turbin angin sumbu horizontal. Sejumlah penelitian telah mengadopsi bentuk dan gerak binatang baik binatang air maupun binatang yang terbang. Anatomi alami pelepah daun pisang menjadi salah satu inspirasi untuk pemodelan profil airfoil. Profil pelepah dari tujuh sampel daun pisang dipetakan dengan menggunakan teknik morfometri geometrik berbasis landmark. Analisis sampel menggunakan metode statistik dan analisis aerodinamis airfoil menggunakan perangkat lunak QBLADE dengan perubahan bilangan Reynolds mulai dari 3E5 hingga 7E5 pada interval 1E5. Ada tujuh sampel dengan variasi profil dan variasi aerodinamis yang konstan. Dari hasil penelitian didapatkan bahwa semua model memiliki koefisien angkat tinggi, koefisien hambat rendah, dan glide ratio tinggi. Sampel 1 pada bilangan Reynolds 7E5 memiliki glide ratio tertinggi dengan nilai 123,07. Dari hasil analisa aerodinamis didapatkan bahwa dalam kondisi kecepatan angin rendah, profil airfoil berdasarkan morfologi pelepah pisang dapat diterima untuk turbin angin.
