摘      要：This paper presents the work carried out to predict the behavior of a 0.6m impulse turbine with fixed guide vanes with 0.6hub-to-tip(H/T) ratio under real sea *** order to predict the true performance of the actual Oscillating Water Column(OWC),the numerical technique has been fine tuned by incorporating the compressibility *** surface elevation verses time history based on Pierson Moskowitz Spectra was used as the input data,Standard numerical techniques were employed to solve the non-linear behavior of the sea *** effect due to ompressibility inside the air chamber and turbine performance under unsteady and irregular flow condition has been analyzed numerically,Considering the quasi-steady assumptions unidirectional steady flow experimental data was used to simulate the turbine characteristics under irregular unsteady flow *** results show that the performance of this type of turbine is quite stable and efficiency of air chamber and the mean conversion efficiency is reduced around 8% and 5% respectively,due to compressibility inside air chamber.
