Performance estimation of bi-directional turbines in wave energy plants
Abstract:
Oscillating water column （OWC） based wave energy plants have been designed with several types of bidirectional turbines for converting pneumatic power to shaft power. Impulse turbines with linked guide vanes and fixed guide vanes have been tested at the Indian Wave Energy plant. This was after initial experimentation with Well＇s turbines. In contrast to the Well＇s turbine which has a linear damping characteristic, impulse turbines have non-linear damping. This has an important effect in the overall energy conversion from wave to wire. Optimizing the wave energy plant requires a turbine with linear damping and good efficiency over a broad range of flow coefficient. This work describes how such a design can be made using fixed guide vane impulse turbines. The Indian Wave Energy plant is used as a case study.[著者文摘]

V. Jayashankar is greatly indebted to SAGA University for providing an opportunity to be in Saga during June 2006 where this work was conceptualized. He is grateful to Prof. Raju and Prof. Ravindran who pioneered the Indian Wave Energy program. He thanks Boby George and Kishore Kumar of IIT Madras for their help.
