Design Procedure of Archimedes Hydro Turbine

Abstract

This study aims to develop a simple-practical design procedure to determine the appropriate size of the turbine's outer radius for any given internal parameters according to the available flow rate through numerical calculation. The calculation is performed using python programming language by combining the existing model of Archimedes turbine, including the power calculation model, turbine flow rate capacity, and losses modeling, into a procedural design calculation to produce the appropriate value. The design procedure could be used to obtain the required and could be able to accommodate the available water flow rate optimally for any given value of each internal parameter and available flow rate. It is obtained that a higher pitch ratio would result in smaller . Moreover, the value of 0.45 would give the smallest size of the appropriate . On the other hand, the higher turbine's inclination angle would require a greater . It is also revealed that the angle of will give the turbine optimum efficiency. In addition, it is also estimated that the Archimedes turbine would be more efficient in a higher available water flow rate. The resulting design shows a good agreement with the installed Archimedes turbine based on the surveyed data at some power plants. Therefore, the proposed design can improve Archimedes Turbine's design by providing the appropriate size of according to the available flow rate without any overflow or underfilling. The design procedure could also provide a practical tool for designing Archimedes turbine.

Generation of Electricity From a Hydraulic Turbine in the Djonou River (Benin)

“…In order to determine the various geometric parameters of the screw, the determination of the radius ratio (ρ), the inclination ratio (λ), the volume ratio (v) and the volume ratio per revolution (λ.v) is paramount [8,16,17,28,45]:…”

“…With S v the area of the right session in (m 2 ) and V the average speed of the fluid flow (m/s). The flow rate Q of water flowing through an Archimedean screw can be broken down as follows [28,36]:…”

“…Several theories and design-simulation procedures have therefore been developed for this turbine by certain authors such as Alonso-Martinez et al [10], Saroinsong et al [11], Purece, and Corlan [12], Dellinger et al [14], Slaboch et al [18], Fiardi [27], Siswantara et al [28], Yulianto et al [29], Dragomirescu [30], Thombare et al [31], Rosly et al [32], Abdullah et al [33], Muller [34], Yulianto et al [35], Rohmer et al [36], Simmons et al [37], Erinofiardi et al [38], Yoosef-Doost and Lubitz [39], Hedia et al [40] followed by an on-site or laboratory experimentation phase discussed by some authors. Ubando et al [41] for their part have examined different methods of manufacturing Archimedean screw turbines such as the 3D printing method still in their early stages of development and additive manufacturing as having a relatively lower environmental impact than conventional manufacturing of turbine blades.…”

The Design and Fabrication of Waterwheels with System Floating Pontoon

“…A conventional hydroelectric power plant is a model that regulates the flow of water from rivers or dams to the water wheel, after which the water flow is directed back to the disposal [9]. Meanwhile, the working principle of hydroelectric power with this water wheel is to try or convert the energy contained in the water flowing in rivers or seas into mechanical energy, which then this mechanical energy can be converted into a form of electrical energy [10]. The main tools that are always needed in making a waterwheel are turbines and generators.…”
