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.
