The fractional step method is used to solve the equations. The numerical simulation is conducted about the simple structure S-shaped rotor with the slit near the tip of the blade to understand the characteristics of the rotor by examination of the torque and the flow around the rotor. As the result of the calculations, the improvement of the power coefficient is found by providing the slit on the blade.}, pages = {1--12}, title = {Numerical simulation of flow around S-shaped rotor with slits on the blade}, volume = {64}, year = {2013} }
