The roles of the chordwise flexural stiffness and ground effect in a rectangular plate undergoing in pure pitching motion have been investigated. Digital Particle image velocimetry (DPIV), load measurement with a 6-axes balance, measurements of the swimming speed and image acquisition of the kinematics of the foil have been done to study the flow patterns and hydrodynamics forces around the flapping flexible plates. The presence of the wall enhances the cruising velocity in some cases up to 25% and the thrust by a 45% , for swept angles of 160 and 240°. The physical mechanisms underlying of this effect are discussed by studying the vorticity dynamics in the wake of the foil. Experimental data of the hydrodynamic forces and moments allowed ...
