Abstract

Small-scale hydropower generation can satisfy the needs of communities located near natural sources of flowing water. The operating conditions of a Michell–Banki Turbine (MBT) are relatively easier to meet than those of other types of turbine, making it useful in places where other devices are not suitable. Moreover, MBT efficiency is almost invariable with respect to flow rate conditions. Nevertheless, such efficiency commonly ranges between 70% and 85%, which is lower than that of other water turbines like Turgo, Pelton, or Francis turbine. The objective of this work is to determine the maximum theoretical efficiency of an MBT and its associated geometrical parameters by implementing Particle Swarm Optimization. The results show a higher effectiveness of the mathematical formulation compared with other cases from literature and show the performance of the optimization method proposed in this study in terms of solution and processing time. Finally, a maximum MBT efficiency of 93.3% was achieved

基于粒子群算法的Michell-Banki涡轮几何参数变化效率优化

小型水力发电可以满足位于天然流动水源附近的社区的需求。与其他类型的涡轮机相比，米歇尔-班基涡轮机(MBT)的操作条件相对容易满足，这使得它在其他设备不适合的地方很有用。此外，MBT效率几乎不受流量条件的影响。然而，这种效率通常在70%到85%之间，低于其他水轮机，如Turgo, Pelton或Francis水轮机。本工作的目的是通过粒子群优化来确定MBT及其相关几何参数的最大理论效率。结果表明，与文献中的其他案例相比，该数学公式具有更高的有效性，并且表明了本文提出的优化方法在求解和处理时间方面的性能。最后，MBT效率最高可达93.3%

期刊介绍： WSEAS Transactions on Applied and Theoretical Mechanics publishes original research papers relating to computational and experimental mechanics. We aim to bring important work to a wide international audience and therefore only publish papers of exceptional scientific value that advance our understanding of these particular areas. The research presented must transcend the limits of case studies, while both experimental and theoretical studies are accepted. It is a multi-disciplinary journal and therefore its content mirrors the diverse interests and approaches of scholars involved with fluid-structure interaction, impact and multibody dynamics, nonlinear dynamics, structural dynamics and related areas. We also welcome scholarly contributions from officials with government agencies, international agencies, and non-governmental organizations.
