Mamoru Ishii

Mamoru Ishii is the Walter Zinn Distinguished Professor of Nuclear Engineering at Purdue University's College of Engineering. His research focuses on two-phase flow modeling, reactor safety systems, and multiphase flow phenomena with applications in nuclear reactor design and cryogenic systems. He holds a Ph.D. from Georgia Institute of Technology and has been a Fellow of the American Nuclear Society since 2021.

• Education:
• Ph.D. Mechanical Engineering, Georgia Institute of Technology, 1971
• M.S. Mechanical Engineering, New York University, 1968
• B.S. Mechanical Engineering, Yokohama National University, 1966

His research interests span two-phase flow experiments, 3-D two-fluid models, interfacial transfer phenomena, severe accident analysis, and advanced light water reactor safety codes. He has pioneered instrumentation development for multiphase flow characterization, including conductivity probes and neural network-based analysis tools.

Recent work emphasizes cryogenic propellant tank behavior modeling, stochastic interfacial area predictions using reinforcement learning, and flow instability analysis in natural circulation systems. His studies often combine CFD simulations with experimental validation in facilities like the Versatile Test Reactor Sodium Cartridge Loop.

• Awards:
  • Fellow, American Nuclear Society (ANS)
  • Honorary Member, Japanese Society of Multiphase Flow

Advising activity includes leading a research group focused on thermal-hydraulics and multiphase flow instrumentation, with contributions to reactor safety codes like RELAP5. His lab develops advanced sensors and computational frameworks for nuclear systems analysis.
