Hydraulic Modeling

Victor M. Lyatkher, PhD, is a professor, engineer, and inventor..  He was educated in Moscow and Leningrad, and has developed and patented numerous processes and machines. These deal mainly with renewable energy sources such as tidal power, water turbines, and vertical axis wind turbines. He developed a new method to forecast long-term variations in the Caspian Sea level, and designed a new kind of low head turbine. Mr. Lyatkher has worked for over thirty years in the wind and hydro-power industry. He has received several prizes and awards for his accomplishments, including the Prize of the Council of Ministers of the USSR, the Award of the Indian Society of Earthquake Technology, and five medals of the All Union USSR Exhibition, gold, silver and bronze.He has published numerous books (in russian) on the subject of renewable energy, and was the original inventor of helical turbine, patented in the USSR in 1983.Alexander M.  Proudovsky, PhD, graduated from the Moscow Engineering and Construction Institute in 1955, received his PhD in 1976 and became Doctor of Technical Sciences in 2000. A renowned expert in the field of hydraulic and hydrothermal modeling of hydraulic structures and nuclear power facilities and a member of the International Association for Hydraulic research since 1974, he has written over 200 articles and 2 books on modeling, both in collaboration with Victor Lyatkher.
