A Wells turbine operating under irregular wave conditions has been analyzed theoretically. It is shown that the turbine performance depends on a unique parameter, including characteristic parameters of the irregular wave, turbine speed and dimensions of the turbine and air chamber. In order to obtain the optimum value of this parameter, a model test has been performed using a computer-controlled wind tunnel, which can simulate arbitrary oscillating flows based on spectra of irregular waves. From this value a set of optimum dimensions of a Wells turbine system can be determined. Furthermore, starting and running characteristics of the Wells turbine have been obtained by a computer simulation. It is possible to predict the optimum value of the parameter and behavior of the output coefficient by computer simulation.
