TY - THES A1 - Miyani, Rushabh Deepak T1 - Design of a Pelton turbine for extremely small water jet diameters (approx. 1 mm) and extremely high nozzle exit velocities (nearly 700 m/s) BT - Application in a hydro-pneumatic energy storage system for single-family homes N2 - In this thesis, the designing and detailing of a patented hydroelectric energy storage system is documented. Hydropower has been one of the oldest sources of electricity for humankind. This thesis is focused on the idea of manufacturing a hydropower plant to a scale that would be feasible and useful for an average household of 4 people. It also includes the processes and guidelines to manufacture the parts of this energy storage. In current times, renewable sources of energy production are increasing, relevant to earlier years, to reduce the dependence of the world energy needs on fossil fuels. Storing this renewable energy is important and due to limited natural resources like Lithium, Nickel etc. for Battery storage, other viable storage technologies need to be developed such as HEES. Hydro-electric Energy Storage (HEES) is an innovative energy storage concept that utilizes hydropower as energy storage. This paper focuses on the design of the Pelton turbine and the nozzle for a prototype of the HEES. Specifically, the runner, the method used to fix the Buckets on a Pelton runner, and the casing for the runner are analyzed in detail. The HEES nozzle is a critical component responsible for precisely directing high-pressure water jets onto the turbine's rotating buckets. The study explores the intricacies of Pelton turbine design, including considerations for bucket width, depth, and attachment methods. The importance of nozzle technology for creating ultra-thin water jets and the design of a casing for the high-speed Pelton turbine is also examined. Material selection is a critical aspect, involving stainless steels with varying properties, including corrosion resistance, strength, and weldability. The evaluation and comparison of these materials lead to informed decisions for prototype and final designs. In the context of manufacturing, various methods, such as CNC machining, forming, stamping, forging, and powder metallurgy, are assessed. A detailed analysis highlights the strengths and weaknesses of each approach. For the HEES prototype, a manufacturing method is chosen based on cost-effectiveness and suitability for aluminium, while the final design leans toward stainless steel and methods that ensure strength, precision, and durability. In the ever-evolving landscape of renewable energy, this thesis contributes to the development of a promising Hydro-Energy Storage System, laying the foundation for sustainable and efficient household energy storage solutions.
