Wells turbine is a self-rectifying airflow turbine capable of converting pneumatic power of the periodically reversing air stream in oscillating water column into mechanical energy. This paper reports the computational analysis on performance and aerodynamics of Wells turbine with the NACA 0021...

A Wells turbine blade for wave power conversion has hysteretic characteristics in a reciprocating flow. The hysteretic loop is opposite to the well-known dynamic stall of an airfoil. In this paper, the mechanism of the hysteretic behavior was elucidated by an unsteady 3-dimensional Navier-Stokes...

This paper provides an overview on the theoretical aspects of a newly developed concept for harnessing the kinetic energy contained in random fluid flows of particles. Because of a number of constraints associated with current power-generating methods of utilisation of random and turbulent...

The European Wave Energy Pilot Plants currently under construction are utilising Wells air turbines to convert oscillating pneumatic energy within the converters to unidirectional energy of rotation for direct coupling to electrical generators. The Wells turbine has also been proposed for future...
