Abstract

Recently, Archimedes screw turbines have been developed to operate as small hydropower stations, because of its reliability to operate with the  low head( less than 5 m) and its low cost of design and operation. In the present study, the influence of the flow rate, shaft  inclination angle, and the number of blades is studied using physical model and numerical model to determine the performance of Archimedes screw turbine at Ramadi Barrages in Iraq. The physical model was made of stainless steel with the following parameters: (the radius ratio is 0.536, the pitch is 70 mm, the shaft angles are 30? ,35? ,40? ,45?). The experimental  work on the physical model is achieved with different flow rates  and angles .The results showing that the highest efficiency is 81.4 % At the angle of 35? and the  flow rate is 1.12 l/s . The maximum energy obtained is 25.13 w at the angle of 45?, the e flow rate is 2.065 l/s, and the efficiency was 72%. Also the results show that the increase in the number of blades increases  the torque and efficiency of the turbine.
