Abstract: The paper contains study of VWAT named analysis and development of vertical wind axis turbine using CFD techniques . The analysis and comparison of various types of blade in this research computational fluid dynamic (CFD) software ANSYS CFX 13 and CATIA were used. Due to its simple design and low construction cost this rotor is mainly used for water pumping as well as wind power on small scale. This investigation was carried out to find aerodynamic characteristics like torque and power of wind turbine rotor model without change in rotor diameter, rotor height and velocity of wind. The main goal of this research is to improve the torque of vertical axis wind mill on the basis of shape of blade , angle of blade and number of blades. Further study on based on angle of blades and number of blades on the curve type and bucket type blades which are effective as compared to other shape of blades. Afterwards results were compared for verification. Study end at the result bucket type shape of blades have angle 300 and 8 number of blades give high performance and torque compared to other blades about 5.86 Nm.
