Dr Nishino obtained his Bachelors and Masters degrees in Mechanical Engineering from Kyoto University in Japan in 2002 and 2004, respectively, and his PhD in Aerodynamics from the University of Southampton in the UK in 2007.
After spending four months as a Visiting Researcher at AGH University of Science and Technology in Poland, he moved to NASA Ames Research Center in the US in 2008. He spent three years at NASA Ames for his postdoctoral research, which contributed to the Subsonic Fixed Wing (SFW) project in the Fundamental Aeronautics (FA) program at NASA.
In 2011 he returned to the UK and joined the Tidal Energy Research Group at the University of Oxford as a Research Assistant. He spent three years in Oxford for his research and teaching (tutoring) mostly in hydrodynamic modelling of marine turbine arrays, prior to joining Cranfield University as a Lecturer in 2014.
Dr Nishino's research expertise is in the areas of aerodynamics, hydrodynamics and marine/offshore renewable energy. He has broad experience in low-speed aerodynamics (boundary layer transition, separation, vortex shedding, wake instability, etc.) and computations of transitional and turbulent flows (using DNS, LES and RANS simulations). He also has experience in thermo-fluid and electro-chemical modelling of fuel cells.
During the last few years he has been working on hydrodynamic modelling of marine turbine arrays. His major achievement so far in this area is the development of multi-scale hydrodynamic modelling approaches to predict (either theoretically or computationally) the performance of a number of marine turbines deployed as a farm. Using this approach, he also derived theoretically a new hydrodynamic efficiency limit of 79.8% for a partial cross-stream array of marine turbines (Nishino & Willden 2012, J. Fluid Mech. 708) compared to the classical "Betz limit" of 59.3% for an isolated turbine.
Since he joined Cranfield University in May 2014, he has been working on a wide range of topics in fluid mechanics, mostly related to marine renewable energy and offshore wind energy applications.
His current research topics include:
- Multi-scale hydrodynamic modelling of marine turbine arrays
- Extended actuator disc theory for wind and tidal turbines
- Aerodynamics of novel vertical-axis wind turbines
- Atmospheric boundary layer interaction with large wind farms
- Formation mechanisms of airfoils stall cells
- Lift enhancement mechanisms of bumpy leading-edge airfoils
- Applications and validation of hybrid RANS-LES approaches
- Applications and validation of laminar-turbulent transition models
