This paper presents development of an algebraic grid generation algorithm applicable to Finite Volume Method for Computational Fluid Dynamics (CFD) calculation of variable pitch twin screw machines. It is based on the principles developed for the uniform pitch rotors with constant cross-section profile. The same algorithm could be also used for rotors with variable profile geometry. Performance...

Wind power is sustainable and prevalent virtually all over the globe. However, conversion efficiency of conventional single-rotor wind turbine (SRWT) still far from satisfactory. The dual-rotor counter-rotating concept among reliable techniques used to enhance a energy device for its renowned effectiveness. This study aims investigate performance Savonius dual/twin-rotor system, particularly in...
