This paper analyses a cycloidal turbine to improve power generation in water distribution systems. The turbine is a straight blade type and adopts a cycloidal system that actively controls the rotor blades to improve the efficiency of the turbine, depending on the operating conditions. By utilizing CFD analysis, a parametric study is carried out to investigate the impact of several characteristics. These characteristics encompassed factors, such as variations in chord length, different tip speed ratios, different case size and various phase angles. The study aimed to explore the relationship between these variables and their effects on the overall system. The optimal parameters are determined, and the performance of the turbine improved by about 25 % compared with that of a fixed pitch turbine.

Abstract

This paper analyses a cycloidal turbine to improve power generation in water distribution systems. The turbine is a straight blade type and adopts a cycloidal system that actively controls the rotor blades to improve the efficiency of the turbine, depending on the operating conditions. By utilizing CFD analysis, a parametric study is carried out to investigate the impact of several characteristics. These characteristics encompassed factors, such as variations in chord length, different tip speed ratios, different case size and various phase angles. The study aimed to explore the relationship between these variables and their effects on the overall system. The optimal parameters are determined, and the performance of the turbine improved by about 25 % compared with that of a fixed pitch turbine.
