Foreword
Pelton turbines are classical hydraulic machines to convert stream flow energy into electricity for medium to high heads. Although invented already in the 1870s by the American Lester Allan Pelton, his runner design is still largely used today in the hydroelectric power industry. Compared to Francis turbines, Pelton wheels offer particularly favourable partial load efficiency degrees and are preferred for low flow rates. They are unrivalled for very high heads above some 700 m, so that their application is mainly in the high mountain regions all over the world. Pelton runners exist in all size classes, from very small Pico hydro applications, e.g. to use tap water from water delivery systems, to the largest units with capacities of more than 400 MW like in the Swiss Bieudron hydropower scheme with a current worldrecord head of 1883 m. Despite the importance of these hydraulic impulse turbines in the hydropower domain, there is only marginal fundamental literature on their theory and design. This textbook of Dr. Zh. Zhang fills this gap, containing a broad analytical treatment of flow processes in real-world Pelton turbines, which renders it so unique and valuable for both the scientific and professional communities. Dr. Zhang not only has a sou
