In summary, an optimum rotor should be a double-stepped rotor, with two paddles equipped with two end-plates which "canalize" the flow inside the rotor. The total height of the rotor should be twice its diameter.

TABLE 1 – Optimal values for main geometrical parameters (giving highest values for Cp).
Let us notice that all the geometrical characteristics leading to the optimal Savonius rotor are only the ones of an "ideal" rotor, i.e. realized independently from the manufacturing and the use necessities, mainly the ones which require the rotor to be rigidified. In particular, a central shaft seems to insure a better mechanical behaviour, such as an external chassis for the rotor. The influence of these two supplementary geometrical parameters will be studied within a numerical simulation. |
