Biography

Dr Nishino studied mechanical engineering at Kyoto University in Japan for his Bachelor’s and Master’s degrees, before obtaining his PhD in aerodynamics at the University of Southampton in 2007.

After his PhD, he received a prestigious NASA Postdoctoral Program (NPP) fellowship to spend three years at NASA Ames Research Center in the US. He came back to the UK in 2011 to take another three-year postdoc position in Oxford.

After the long and productive postdoc period, he took a Lectureship in Fluid Mechanics at Cranfield University in 2014. In September 2018, he returned to the University of Oxford to take a Departmental Lectureship in Civil Engineering Fluid Mechanics.

Research Interests

Dr Nishino’s expertise is in the areas of (theoretical and computational) fluid mechanics and offshore renewable energy, such as wind and tidal-stream energy. During his first postdoc period at NASA, he learnt a variety of advanced modelling techniques for complex turbulent flow simulations. He then extended his fluid mechanics research to offshore renewable energy in his second postdoc period in Oxford. His major achievement during this time was the development of multi-scale coupled modelling approaches to predict the efficiency of a large number of tidal-stream turbines deployed as a farm. In particular, he mathematically derived a new theoretical upper limit of 79.8% for the efficiency of an isolated cross-stream array of turbines (Nishino & Willden 2012, J. Fluid Mech. 708) compared to the classical "Betz limit" of 59.3% for a single isolated turbine.

More recently, Takafumi extended and applied his multi-scale flow analysis to the modelling of large wind farms, partly in collaboration with the UK Met Office. One of his current research goals is to develop a novel scientific approach for fully coupled wind turbine/farm design optimisation, by combining his multi-scale wind turbine/farm flow analysis with a regional-scale numerical weather prediction (NWP) model.

Apart from wind and tidal energy research, he is also working on a range of fundamental problems in aero/hydrodynamics, such as laminar-to-turbulent transition and separation of the boundary layer, static and dynamic stall of aero/hydrofoils, stability and mixing characteristics of turbulent wake behind a bluff body, and flow-induced vibrations.
