THEORETICAL STUDY FOR AERODYNAMIC PERFORMANCE OF HORIZONTAL AXIS WIND TURBINE

Abstract

This work is based on theoretical mathematical model of aerodynamic forces acting on the blades of horizontal axis wind turbine and influence of different parameters on power efficiency and energy production has been investigated. It has been chosen an profile airfoil type NACA 2410 with different parameters (number of turbine blades (2–5), tip speed ratio (4–20) and ratio of coefficient forces (25–100)). Evaluation these parameters by using iterative solution and obtained a good results for turbine efficiency (0.45-0.51) when the number of blade is (3) and local tip speed ratio (5-7) with coefficient force (100) for chosen profile airfoil.
