Currently, people think about the Drag type of vertical axis wind turbine as a reliable wind machine to save in future energy supply. The advantage to this emerges from the building and maintaining cost, which is cheaper than the wind turbines with Horizontal axis. Nevertheless, such rotor is facing problems from efficiency. This study proves the improvement of Savonius rotor performance, a basic geometry of drag machine, as dependent to partial differential equation. The report shows investigations conducted to show the effect of geometrical configuration on the rotor performance in terms of coefficient of torque and power, and power output. In proving the above case, the study will consider simulation Computerized Fluid Dynamics, which will help in analyzing the flow, attributes of the rotor. The equations of continuity and Reynolds Averaged Navier-Stokes together with the realizable K- epsilon turbulence model will help in the judgment of the case. The results obtained shows that partial differential equation is important in the enhancement of the performance of the savonius rotor. Likewise, the performance coefficient of an optimal rotor reaches 0.2 with a rotor having two blades and H/D = 6:1, e = 0.3, ÃÂµ = 1800.
