Small hydropower is increasingly important on a global level, and the possibility of local power generation could considerably improve living conditions in rural areas in developing countries. This thesis presents a numerical modelling approach to improve the design of low-cost machines like water wheels for increased hydraulic efficiency. Using a Computational Fluid Dynamics (CFD) approach, it explores effects of blade geometry, optimal wheel-width to channel-width ratio and channel bed conditions upstream and downstream to improve performance. With a power rating in the low kilowatt range,…mehr

Small hydropower is increasingly important on a global level, and the possibility of local power generation could considerably improve living conditions in rural areas in developing countries. This thesis presents a numerical modelling approach to improve the design of low-cost machines like water wheels for increased hydraulic efficiency. Using a Computational Fluid Dynamics (CFD) approach, it explores effects of blade geometry, optimal wheel-width to channel-width ratio and channel bed conditions upstream and downstream to improve performance. With a power rating in the low kilowatt range, low-head hydropower machines seem to have a clear potential for small-scale energy generation.

Autorenporträt
Pradeep Narrain is a mechanical engineer who, after having worked on hydraulic modelling of components for transmission systems in the automobile industry, started work in the field of CFD. He has worked on various applied research projects involving external an internal flow modelling using CFD at the Institute of Applied Research "Energetic Systems", Esslingen University, Germany Upon completion of his MSc. in Water Resources and Engineering at the University of Stuttgart in 2009, he moved to UNESCO-IHE at Delft, the Netherlands to begin his PhD on very low head hydropower machines. His PhD focussed on low head hydropower, its importance on a global scale, its contribution to local power generation and the implementation of CFD for flow analysis. While continuing working on his PhD, he returned to Esslingen University in 2012 to work at the Faculty of Automotive Engineering. He is a tutor and laboratory engineer in the Laboratory for Car-Body Engineering. He works on CAD construction methodology of free-form surfaces using the industrial software-packages. He also works with CAD car-body models and design-space in a Virtual Reality environment, including Rapid Prototyping of CAD models, reverse-engineering and migration of laser-scan data of clay-models into a virtual/CAD environment.
