5 EXPERIMENTAL VALIDATION where D is a positive number . either a constant ( case A - Wells turbine ) or a function of time ( case B - variable geometry turbine ) . Note that in neither cases compression work is done by the turbine .

This general trend is verifyed both when the Wells turbine and the variable geometry turbine are used . However , the last turbine allows a better hydrodynamic coupling between the wave and the system , giving an excess of about 7 ...
