Casing Treatment of a Wave Energy Extracting Turbine

Performance of wave energy extracting turbine used in oscillating water column wave energy system depends on the turbine blade tip leakage flow. Computational study of flow through the turbine by solving Reynolds averaged Navier-Stokes equations were carried out using ANSYS CFX® v14.5 commercial code. The main objective of this paper was to study the effect casing treatment and the vortex patt…
