Effect of freestream turbulence on the coherent dynamics of a wind turbine wake
Neelakash Biswas, Oliver R. H. Buxton
The wake of a model wind turbine exposed to incoming freestream turbulence (FST) with a variety of turbulent characteristics is studied through Particle Image Velocimetry experimen…
Energy exchanges between coherent modes in the near wake of a rotor model at different tip speed ratios
Neelakash Biswas, Oliver R. H. Buxton
In this work we investigate the spatio-temporal nature of various coherent modes present in a rotor wake using a combination of new PIV experiments and data from Biswas and Buxton…
Effect of tip speed ratio on multiscale coherent dynamics in the near wake of a model wind turbine
Neelakash Biswas, Oliver R. H. Buxton
The near wake of a small-scale wind turbine is investigated using Particle Image Velocimetry (PIV) experiments at different tip speed ratios (). The wind turbine model had a nac…
Puff-like instability in laminar to turbulence supercritical transition of round jets
Neelakash Biswas, Aviral Sharma, Sandeep Saha +1
We explore the laminar to turbulence transition of round jets at low Reynolds number (Re < 1000) using a novel experimental setup and linear stability theory (LST). The setup has a…
