Performance and wake characteristics of tidal turbines in an infinitely large array
Pablo Ouro, Takafumi Nishino
The efficiency of tidal-stream turbines in a large array depends on the balance between negative effects of turbine-wake interactions and positive effects of bypass-flow accelerati…
Two-scale momentum theory for time-dependent modelling of large wind farms
Takafumi Nishino, Thomas D. Dunstan
This paper presents a theory based on the law of momentum conservation to define and help analyse the problem of large wind farm aerodynamics. The theory splits the problem into tw…
Generalisation of the two-scale momentum theory for coupled wind turbine/farm optimisation
Takafumi Nishino
An extended theoretical approach is proposed to predict the average power of wind turbines in a large finite-size wind farm. The approach is based on the two-scale momentum theory…
Tuning turbine rotor design for very large wind farms
Takafumi Nishino, William Hunter
A new theoretical method is presented for future multi-scale aerodynamic optimisation of very large wind farms. The new method combines a recent two-scale coupled momentum analysis…
Beyond the Betz Theory - Blockage, Wake Mixing and Turbulence
Takafumi Nishino
Recent analytical models concerning the limiting efficiency of marine hydrokinetic (MHK) turbines are reviewed with an emphasis on the significance of blockages (of local as well a…
Low-Order Modelling of Blade-Induced Turbulence for RANS Actuator Disk Computations of Wind and Tidal Turbines
Takafumi Nishino, Richard H. J. Willden
Modelling of turbine blade-induced turbulence (BIT) is discussed within the framework of three-dimensional Reynolds-averaged Navier-Stokes (RANS) actuator disk computations. We fir…
