Analysis of Flow through Ocean Energy Harvesting Bidirectional Impulse Turbine

Analysis of Flow through Ocean Energy Harvesting Bidirectional Impulse Turbine

Oscillating water column based wave energy device uses bi-directional flow impulse turbine. In this paper, a computational analysis of an impulse turbine has been performed using Ansys-CFX 14.0 code. Initially, a CAD model was prepared and unstructured meshing strategy was implemented in the flow do...
