	abstract = {Previous research on the vertical axis turbines efficiency has used blades with a typical\&nbsp;static camber to improve the turbines efficiency. Typically, the static camber increases the\&nbsp;drag force, which affects negatively the optimal harvesting of energy. The present study\&nbsp;proposes deformable blades that change their shape relative to their angular position. The\&nbsp;new blade shape is achieved by deforming the airfoil camber line via a sinusoidal rounded\&nbsp;arc. The computed results show that the present type of deformation involves two typical\&nbsp;flow control mechanisms. Firstly, a leading edge control that alters the flow angle of attacks\&nbsp;and therefore the leading edge vortex (LEV) time of growth. Secondly, this type of\&nbsp;deformation comprises a trailing edge control that affects the physical size and strength of\&nbsp;the LEV. The lift force can be effectively increased. As a main result, the turbine power\&nbsp;coefficient appears to be higher by about 20\% for the optimal operating conditions\&nbsp;},
