Optimization performance and blade geometry of pico-scale turgo turbine by response surface design

The PSTT (pico-scale Turgo turbine) is a suitable power plant for isolated or rural areas. A mathematical understanding of the energy conversion process from water to the blade is required to increase PSTT performance. This study proposes an analysis of PSTT energy conversion in a thorough discussion of the effect of water velocity toward blade shape. The previous studies are required for the verification of analytical results. According to the findings, the calculation results in an average 3.86% deviation from earlier studies. As a result, the proposed analytical approach has been verified. The optimum conditions for PSTT, according to the analytical results, are a 20° angle of attack, a 40° inlet blade angle, a 10° exit blade angle, a 60° blade angle, and a 10° angle of inclination of the blade. This geometry generates 90.22 W of mechanical power with 91.97 % efficiency.
