Design and Investigation of Archimedes Screw Turbine: Influence of Inclination Angle on Power Production
摘要
The Archimedes screw turbine (AST) is a type of turbine that produces micro-hydro power that can operate at low heads. In this article, the performance of AST is experimentally investigated for the angle of an inclination. This study aims to analyze the effect of variations in the turbine screw shaft angle on the shaft rotation, output power, current, and voltage generated. The AST turbine’s lower inclination angle (25°) results in higher efficiency. The test results show that the optimum inclination angle is obtained at 35° for water discharge 0.011 m3/s delivering a torque of 2 N.m.
