ABSTRAKDewasa ini isu krisis energi terus berkembang, dimana dibutuhkan energi terbarukan agar dapat menggantikan energi fosil yang menurut perkiraan akan segera habis, sehingga apabila tidak ada energi yang terbarukan maka manusia akan kekurangan energi. Salah satu upaya pengembangan energi terbarukan adalah dengan pengembangan pembangkit listrik bertenaga air yang bernama Picohydro, dimana Picohydro ini dapat menghasilkan energi listrik kurang dari 5 kW. Hal ini terutama diaplikasikan untuk debit air yang rendah. Penelitian ini ditujukan untuk mensimulasikan turbin crossflow pada komponen pembangkit Picohydro. Turbin berdiameter 0,135 m, diameter shaft 0,03 m, diameter inlet 0,04 m dan jumlah sudu sebanyak 18 buah. Simulasi menggunakan software desain dan CFD Fluent. Desain terdiri dari inlet, outlet, fluida rotate dan wall. Inlet diatur dengan kecepatan 6 m/s, turbulent intensity 5% dan hydraulic diameter 0,04 m. Fluida rotate diseting pada kondisi moving reference frame. Equisize skew mesh diatur dengan rentang nilai 0-1 dan aspect ratio mesh dari desain bernilai 1-3. Simulasi dari turbin crossflow dengan sudu 18 buah menghasilkan kecepatan rotasi sudu sebesar 16.5 rad/s atau angular velocity sebesar 157.5633 rpm, dan momen sebesar 290.39 Nm. Sehingga daya optimal yang dihasilkan adalah sebesar 4791 watt (4.791 kw). Kata kunci: picohydro, crossflow, CFD fluent. ABSTRACT Today the issue of energy crisis continues to grow, where renewable energy is needed in order to replace the fossil energy that is expected to run out soon, so that if there is no renewable energy then man will lack energy. One of the renewable energy development efforts is with the development of a water

“…The mechanical output power Pout at the wheel axle is still lower than P gr and P net , because different power losses occur in the wheel and headrace between the sluice gate and the wheel. Quaranta and Revelli [21] stated that six main kinds of power losses may occur in the wheel and headrace: (1) impact losses include the impact of the entry water on the blades (L imp ) and the impact of the blades on the tailrace (L t ), (2) leakage losses are water losses through the slits between the buckets and the channel (L Q ), (3) friction losses are due to mechanical friction at the shaft supports (L g ) and to drag effect of the water (contained in the buckets) on the channel bed (L bed ), (4) hydraulic losses may occur when the residual power of the water in the last bucket is lost in the tailrace (L h ) and (5)(6) there are the hydraulic (L c ) and leakage (L Qu ) losses in the headrace between the sluice gate and the wheel. P out can be calculated by:…”

In recent years, the global warming and efficient usage of energy sources are become most attractive issues. Furthermore, renewable energy technologies play an important role in addressing global energy and environmental challenges. Among the renewable energy technologies, hydropower is considered to be the most advanced and mature, providing some level of electricity generation in more than 160 countries worldwide. Micro-hydropower plant is in the category of small-scale hydropower projects, and it provides an affordable, reliable, economically viable, socially acceptable and environmentally energy alternative for rural area. In this article, micro-hydropower technologies, design and performance characteristics, power losses, mechanical powers and efficiencies for the waterwheel systems such as breastshot, overshot and undershot are reviewed in detail and compared each other. In addition, the development of worldwide hydropower capacity is discussed, and the top countries in terms of total installed capacity are reported and investigated.Keywords: Micro-hydropower, Waterwheels systems, Breastshot, Overshot, Undershot. Mikro-Hidroelektrik Teknolojileri ve Su Çarkı Sistemlerinin TasarımÖzelliklerine Genel Bir Bakış ÖzetSon yıllarda, küresel ısınma ve enerji kaynaklarının verimli kullanılması en cazip konular haline gelmiştir. Ayrıca, yenilenebilir enerji teknolojileri, küresel enerji ve çevre sorunları açısından önemli bir rol oynamaktadır.

“…As shown in Figure 5, the reaction turbine rotor has two pathways where the working fluid under high pressure enters into the inlet nozzle and expands out from the exit nozzle. The expansion ratio between the inlet nozzle and the outlet nozzle is very high and spins the rotors at very high speed [6]. …”

This paper investigates the computational modeling of a binary organic Rankine power cycle. The computer model has been generated to aid the design and manufacture of apparatus that will be utilized during experimentation on the geothermal resources in Victoria, Australia.Suitable technology to utilize the low grade heat from the available geo-fluids has been explained to connect the recent technology with the new approached design. The paper involves the design of the heat engine with the reaction turbine. In addition, theoretical analysis and performance predictions have been presented briefly in the paper to compare between different diameters for the reaction turbine in the organic Rankine cycle engine with power and efficiency. In this paper, realistic recommendations will be discussed to the best of the geothermal energy as sustainable energy resources to be useful for achieving the Australian target. The binary cycle is modeled to evaluate the output power and the efficiency. A computer model for binary cycle is presented in this paper. Thermal-mechanical energy conversion efficiency is predicted using the computer modeling and presented in the analysis.
