Abstract
The objective of the paper is to design a turbine blade of Archimedean Spiral-Type Wind Turbine (ASWT) and to conduct an external flow analysis to determine the variation of velocity and pressure of air while it flows through the blade. The design and Computational Fluid Dynamics analysis is performed with the aid of SOLIDWORKS 18 software. The design of turbine is enhanced to improve the power coefficient by studying the effect of various parameters such as pitch, opening angle and tip speed ratio (wind velocity). The turbine blade design is optimized for achieving optimum power coefficient. Simulation is conducted at a wind velocity of 4 m/s for the blade with 750 mm radius. Pitch and opening angle of the blade are 1125 mm (1.5 times radius) and 60áµ’ respectively. The maximum, average and minimum values of velocity and pressure is also found out through simulation.
