“…In order to improve the performance of this technology, several investigations have been carried out in the literature. In the work of Yulistiyanto et al [20], Maulana et al [13], Alkistis et al [19], Maulana et al [15], Abdul et al [9], Khan et al [21], Betancour et al [22], Abdillah et al [23], Imawati et al [24], Eswanto et al [25], Erinofiardi et al [26] the authors studied the influence of the geometric and hydraulic parameters of the Archimedes screw, namely the angle of inclination of the shaft, the number of blades, the variations in flow, the slope of the shaft , the direction of the axis of rotation, the speed of rotation, its angle of slope, the diameter ratio between the inner and outer diameters, the length of the axis and the pitch on the power and efficiency of the screw. According to the work of Warjito et al [6], the authors believe that the Archimedes turbine has no fixed design theory.…”
