Figure 1. Variation of Pressure Coefficient with Rotating Speed of the Rotor for
Different Geometries of the Rotor such as Basic Geometry of the Rotor, Rotor with
Fillets, Rotor with 70-Degree Blade Angle and Rotor with 90-Degree Blade Angle.
Initially, numerical simulations of rotor geometries such as the basic
geometry of the rotor, rotor with fillets, rotor with 70-degree blade angle, and
the rotor with 90-degree blade angle were carried out for different rotational
