UCL - 1m Laboratory Tests

March 2012

A comparative study of curved and flat paddles, each 1m wide, at UCL

Laboratory tests have been performed on a selection of curved and flat paddle shapes, to assess the relative importance of the CCell curvature in absorbing wave energy in the wave flumes at UCL.

The curvature of the CCell paddles not only increased the forces and power delivered to the piston, but there was also a noticeable reduction in turbulence around the paddles. Crucially, the tests demonstrated that the curved CCell paddles would extract energy from the waves both within a wave crest and wave trough.

The tests have validated the concept, but we remain concerned about the validity of the larger performance gains observed as the paddles occupied approximate 2/5th of the laboratory tank's width.
