Oscillating Water Column Geometrical Factors and System Performance: A Review

Abstract: Ocean waves that impact along the coast are among the most promising renewable energy sources that can be extracted from the environment. The ocean's energy can be extracted by a few methods and converted from kinetic energy into electrical energy using turbine blades and power generators installed in areas with strong waves. The best and most widely established wave energy converters use an Oscillating Water Column (OWC) conversion concept. During the past few years, numerous research projects have been condu… Show more

“…This behavior is likely caused by varying impact of the induced pressure drop (see Figure 8) between the upstream and downstream sides of the turbine. On one hand, this pressure difference acts as a power booster, while on the other hand, it reduces the power coefficient of the machine, as deduced from Eq.5 [17,18,19]. In Figure 8, the variation of the pressure drop between the upstream and downstream sides of the turbine is shown as a function of its rotational speed for all studied oscillation frequencies.…”

“…Therefore, tidal and river energy could offer a good solution to mitigate these issues. However, there are several challenges associated with VATs, like poor performance, poor rotation, low stream inlets, and problems associated with self-starting [17,18].…”
