Pengujian Turbin Air Pusaran Gravitasi dengan Variasi Overlap Ratio Rotor
نویسندگان
چکیده
The gravitational water vortex turbine is a system that can convert the energy from artificial by means of drained through basin outlet to kinetic rotor rotation. This type able produce despite low head flow. Many researches were conducted improve efficiency this changing shape basin, or rotor. Meanwhile, Savonius has good starting rotation and ease fabrication, but efficiency. One way increase apply gap between blades which called Overlap Ratio (OR). In research, with conical-shape was combined various-OR rotors area proportion 26,88% without endplate effect observed turbine. volume flowrate channel maintained constant at 0,005 m 3 /s while mass added gradually for torque measurement using rope brake dynamometer. result showed all rotors, greater occurred in rotational speed. Moreover, OR 0,15 had mechanical around 22,78% 27,18% than 0. higher maximum variation 26,88%.

The Ocean has provided a new avenue in the quest for renewable energy. One potentialsource of energy is marine current, which is harnessed using either vertical or horizontal axis turbines.This paper describes a particular type of vertical axis turbine which is suitable for low current velocityapplications. The simulation of Savonius-type turbine, which hitherto has never been proposed formarin...
متن کاملJohn J. Sheridan, DDS, MSD, on air-rotor stripping.
DR. SHERIDAN Prior to ARS, there was ab solutely nothing in the literature pertaining to stripping the proximal surfaces of buccal teeth, because for decades we banded them and these surfaces were covered with metal. That changed abruptly when bonding became the standard. All proximal surfaces became approachable and, therefore, strippable during any stage of treatment. Also, traditional stripp...
