Turbin angin digunakan untuk mengkonversi energi angin menjadi energi listrik melalui sudu turbin lalu diteruskan ke generator. Beberapa pengembangan telah dilakukan tetapi masih ada persoalan seperti rusaknya turbin angin dan rendahnya daya serap angin. Berdasarkan permasalahan tersebut dilakukan perancangan sudut sudu bilah dengan variasi sudut 0º, 10º, dan 15º. Perancangan dil…
Airfoil is a cross-sectional form that can result in lift force or aerodynamic effects when passing through an airflow. An understanding of crustaristic aerodynamics includes lift efficiency, drag coefficient and Cl/Cd ratio. In this study numerically investigated different types of airfoils to improve the efficiency of wind turbines used in low-speed wind regions. One method of airfo…
The gravity vortex turbine is a type of microhydro power plant (PLTMH) that uses a vortex to turn the turbine. To increase its efficiency, the flow velocity and vortex height must be increased. So that it is necessary to pay attention to the variables that influence it, such as the inflow of water and the size of the basin. However, until now investigating the comparison of the two b…
Electrical energy is one of the primary human needs which continues to increase. Dependence on fossil energy and the minimal use of renewable energy is one of the weaknesses in the application of energy policies. Hydroelectric power is an option in utilizing renewable energy sources. The availability of water in Indonesia has the potential to be used as a renewable energy source. …
Jeranjang Pembangkit Listrik Tenaga Uap (PLTU) (Steam-Electric Power Station) is a steam power plant with a capacity of 3 x 25 megawatts (MW) on Lombok island. One measure of the efficiency of a generating unit is its heat rate value. The heat rate is defined as the amount of fuel energy required to produce 1 kilowatt-hour (kWh) of electrical energy. This study aims to determine the heat…
Hydroelectric power plants or commonly referred to as micro hydro which usually utilize water with high water fall heights. As for the low water fall heights have not been maximally utilized. This is a reference to take advantage of the flow of water that has a low fall height by changing into vortex flow. A vortex turbine is a smallscale water-powered power plant that uses the vortex or …
the developments in research using computational development in a variety of turbulence analysis models that have developed now and have been applied to various CFD package programs, the boundary condition range of a simulation can be made according to the goals we want. Considering the flow in testing airfoil for the use of wind turbine blades at low Reynold’s numbers is so difficult to…
The Micro Hydro Power Plant (PLTMH) which is very often used today is the Cross Flow Turbine. The reason is because of the high level of efficiency using low pressure and speed, the flow of water flows through the entrance of the pipe and is regulated by the guide vane and guide in to the turbine blade rotation. After the water has passed the turbine blade rotation, the water is in the opposite…
