We present flow analysis of a wave-energy air turbine,specifically a Wells turbine. The analysis is based on the Streamline-Upwind/Petrov-Galerkin (SUPG) and Pressure-Stabilizing/Petrov-Galerkin (PSPG) methods and discontinuity-capturing directional dissipation (DCDD). The DCDD,first introduced to complement the SUPG/PSPG method in computation of incompressible flows in the presence of sharp solution gradients,was also shown to perform well in turbulent-flow test computations when compared to the Smagorinsky large eddy simulation model. Our computational analysis of the Wells turbine here,with results that compare favorably to the available experimental data,shows that the DCDD method performs well also in turbomachinery flows.
