Performance of vertical axis water turbine with eye-shaped baffle for pico hydropower

Free-Spinning Numerical Simulation of a Novel Vertical Axis Small Water Turbine Generator for Installation in a Water Pipeline

“…Then, in Eq. ( 1), it was defined the equation of continuity, where rho is the density of water, t is time, and represents the three spatial components of the fluid velocity ,, u v w [14]. The momentum equations are defined by Eq.…”

“…The CFD analysis of both wheels of the vertical-axis small water turbine for installation in the pipeline was carried out using Autodesk Flow Simulation software. In this study, the results from all the three different cases above can be summarized as following: With the analysis of the optimum angle for placing water turbine blades, it was discovered that the shape with the arc, as well as the KMUTT Blade, which was redesigned and compared to different airfoil shapes, as shown in Figure 8, and is commonly used to create turbine blades today [14], will result in a good lifting force. The results showed that the KMUTT blade was able to produce the best L/D ratio at an angle of 12 degrees, making the 12-degree angle a good choice to create the water turbine wheel and achieve the results shown in Figure 7.…”

“…And higher production costs will be required. The present water turbine generators for installation in pipelines have been studied, investigated, and introduced through numerous research projects [14][15][16][17][18][19]. Therefore, the researchers wanted to propose a design for a wheel turbine generator and a small vertical turbine wheel unit for installation in a novel pipe.…”

Diseño de pico-turbinas hidráulicas axiales para la recuperación de energía en redes de distribución de agua

“…Dada las bajas potencias absorbidas por las turbinas objeto de estudio de este trabajo (≤ 5 kW) y la alta variabilidad de condiciones de funcionamiento encontradas en las RDA, se puede considerar que la opción más viable para la captura y almacenamiento de esta potencia es la utilización de baterías, las cuales a su vez pueden usarse en aplicaciones como la alimentación de sistemas de detección de fugas (Du et al, 2018;Hu et al, 2020). En consecuencia en este capítulo se plantea deducir las ecuaciones de comportamiento adimensional del sistema hidráulico-eléctrico acoplado para almacenamiento de energía en baterías.…”
