MODELING AND DESIGNING OF SMALL WIND TURBINE BLADE
2020
Wind turbines working at lower wind speed shows the bad performance due to laminar flow of
wind leads to laminar separation. This problem usually occurs at a lower Reynolds number and lower wind
speeds always have a lower Reynolds number. In this paper a wind turbine blade of 2KW of capacity working
on lower wind speed has been designed. At first in the airfoil section the low Reynolds number airfoil
E387,S1223,SD7080,NACA2414 is selected and their airfoil characteristics is investigated. After investigation
the characteristics of airfoil, blade is designed in q blade software. The simulation is done at different
Reynolds number. From the simulation results it is found that the maximum power of 1750W is obtained at
power coefficient of 0.27 at Reynolds number of 422731.
