Advances in Steam Turbines for Modern Power Plants

Tadashi Tanuma is a Professor at Teikyo University, Japan. He is the head of the Laboratory of Fluid-Structural Simulation and Design in the Strategic Innovation and Research Center. He also works for the Graduate School of Science & Engineering and the Department of Mechanical and Precision System Engineering in Teikyo University. Professor Tadashi Tanuma began his career as a development mechanical engineer in 1980 at Turbine Factory, Toshiba Corporation, Japan. He led the Turbomachinary Development Group from 1993. Subsequently, he joined the Steam Turbine Design Department in Keihin Product Operations of Toshiba Corporation. He developed and designed Toshiba 52-inch last stage long blade for nuclear power steam turbines and steel 40 and 48-inch last stage long blade for thermal power steam turbines as an aerodynamic engineer and led many research and development programs for steam and gas turbine efficiency enhancement technologies. He was the President of the Gas Turbine Society of Japan (2015).
